VSA R Training (Fall 2022) (2024)

I've followed the same code but I'm getting an error message as shown below. Any idea why? Thanks! :)

Seems like it's a warning message rather, not an error message. Would still like to understand more how to fix/navigate it. Thanks! :)

While trying to download the janitor package, I am getting an error message "Error in library(janitor) : there is no package called ‘janitor’ "Can you please tell me what to do now?

Just a word of advice from beginner. I just watched: https://vimeo.com/320973807 02:47. this is essential slide and explanation for me. I could not compute which of the forthcoming functions work on rows and which on columns.

For a number of attempts, I kept getting this error:Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(j library(tidyverse) Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘cellranger’

After some googling, I just installed "cellranger" separately and that seemed to resolve the issue. Is this common or do I have something set up incorrectly?

Should I be worried about all of this red text? :Warning: 4859 parsing failures.row col expected actual file5001 TVHrsDay 1/0/T/F/TRUE/FALSE 2_hr 'data/nhanes.csv'5002 TVHrsDay 1/0/T/F/TRUE/FALSE More_4_hr 'data/nhanes.csv'5003 TVHrsDay 1/0/T/F/TRUE/FALSE 4_hr 'data/nhanes.csv'5004 TVHrsDay 1/0/T/F/TRUE/FALSE 4_hr 'data/nhanes.csv'5005 TVHrsDay 1/0/T/F/TRUE/FALSE 1_hr 'data/nhanes.csv'.... ........ .................. ......... .................See problems(...) for more details.

Hello!I'm getting this error message: Error in library(janitor) : there is no package called ‘janitor’

Not sure what to do about it to be able to use clean names.

Thanks!Juan

For anyone who needs it, you can use this URL in place of the bit.ly one to access the course materials as a zip file: https://codeload.github.com/rfortherestofus/fundamentals/zip/refs/heads/master

You can definitely do that, though I think there are some caveats to consider. I recorded a video to explain my thinking and show you how I'd do things. The code I show in the video is here.

After executing the 2nd code chunk instructions the following message was generated:Column specificationDelimiter: ","chr (13): SurveyYr, Gender, AgeDecade, Race1, Education, MaritalStatus, HHIncome, HomeOwn, Work, HealthGen, ...dbl (9): ID, Age, Weight, Height, BMI, DaysPhysHlthBad, DaysMentHlthBad, SleepHrsNight, PhysActiveDays

i Use spec() to retrieve the full column specification for this data.i Specify the column types or set show_col_types = FALSE to quiet this message.

Should I be worried about these last two rows?

Hi there! Getting this code when loading janitor.The following objects are masked from ‘package:stats’:

chisq.test, fisher.test

I know that this may be ok for our purposes now but I love chi square & fisher's tests! Any way to keep them? Or are they done in another package?

Whenever I try these "usethis" commands, I always get this feedback:

Error in curl::curl_download(url = url, destfile = destfile, quiet = quiet, : Recv failure: Connection was reset

Never mind - ended up using the codeload from github.

Hi there

I keep getting errors about the janitor package. I dont see it listed in the tab for packages either. Any other suggestions?

> library(janitor)Error in library(janitor) : there is no package called ‘janitor’> library (janitor)Error in library(janitor) : there is no package called ‘janitor’> install.packages (janitor)Error in install.packages : object 'janitor' not found> install.packages(janitor)Error in install.packages : object 'janitor' not found

I keep getting this error message:Error in read.csv("data/nhanes.csv") %>% clean_names() :could not find function "%>%"

I have the following libraries loaded with the code below. What am I missing?

library(tidyverse)library(janitor)library(skimr)

nhanes %  clean_names()

This all worked for me when I did the sample exercise. I am now trying to work with some SurveyMonkey data I have from an actual survey I am working on, and having some difficulty. First of all, the variable names are insanely long (all the words of every question). I don't know if there is a better way to deal with it, but I was thinking that I would just rename all of them (e.g., rename " x2_what_grade_are_you_in" to "grade"). This is tedious, but maybe necessary? Making it more tedious, though, is the fact that even though I ran clean_names, the autocomplete function doesn't seem to be working. Any thoughts on what the problem could be? Typing out all the words in every one of these very long variable names would be a huge pain... Thanks for any guidance!

Where do I find the data-wrangling-and-analysis-exercises.Rmd file ??

Hmmm I have an error getting started:> library(usethis)Warning: package ‘usethis’ was built under R version 4.2.3Error: package or namespace load failed for ‘usethis’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):namespace ‘rlang’ 1.0.6 is already loaded, but >= 1.1.0 is required

When I try to do the last step, I get this message"Error in read_csv("data/nhanes.csv") %>% clean_names() :could not find function "%>%"Not sure what I'm doing wrong. I'm having a lot of trouble with RStudio tonight.

Hi David,Previously I was able to get half-way through the select exercise assignments. However, notwwhen I run the code from the start, run the clean_name function- I use the following codeLnhanes%clean_names()But I get the following error message: Use spec() to retrieve the full column specification for this data.i Specify the column types or set show_col_types = FALSE to quiet this message.>

Hello,I have been trying to practice lesson but on a single file and this is the error message I got after trying to knit the entire document, which, as a result, makes no output:
