Common Troubleshooting

Before anything else, try to restart the R session: * In R studio, on top go to “Session” * “Restart R”

Can not install the package

Note that in case you get the following error:

InternetOpenUrl failed: 'An error occurred in the secure channel support'

Enter the command:

setInternet2(TRUE)

Alternatively, you may add to .Rprofile or Rprofile.site the following line:

options(download.file.method = "wininet")

Unable to move temporary installation

One common errors during the package installation is linked to the antivirus “real time file system protection”. The following will fix the problem:

trace(utils:::unpackPkgZip, edit=TRUE)

Edit line 140:

Sys.sleep(0.5)

to:

Sys.sleep(2)

Error in strptime(xx, f, tz = tz) : unable to identify current timezone ‘C’: please set environment variable ‘TZ’


## enter this commaned to set up the time zone - you may change it to another anotherone.
Sys.setenv(TZ='GMT')

## Now you can check...
Sys.timezone()
Sys.getenv("TZ")

The application crashed

If the application (graphic interface) crashes, make sure that all packages necessary are loaded with:

source("code/0-packages.R")

Also make sure that you downloaded your data in the right format: * Export as XLS * XML values and headers * Include groups in headers * ‘Group separator’ as dot (‘.’)

Error when building the dictionnary or configuration file

If you see this message (or similar error):

Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection

It is most likely because you have the form, dictionary or data set open on your computer. If you close it and start over, the problem should be fixed.

Error when loading packages

If you get this error:

Error: package or namespace load failed for 'rJava'

It could be because you have a 64bit version of R, but have a 32bit version of Java. Check this thread for guidance: https://stackoverflow.com/questions/37735108/r-error-onload-failed-in-loadnamespace-for-rjava

Installing pacckage library on a one-drive folder

as explained here: https://www.accelebrate.com/library/how-to-articles/r-rstudio-library, Go and edit to your Rprofile file by adding

my custom path

myPaths <- .libPaths() myPaths <- c(myPaths[2], myPaths[1]) # switch them myPaths <- c(myPaths, ‘C:’) # add new path .libPaths(myPaths) # reassign path
