adding an `ifelse` like statement or `trycatch` to code for reading in files












0














I am trying to read in some data using a combination of list.files etc.



I have a character value called myfiles and looks like the following;



[1] "E:/IRI Data/External/demos12.csv"
[2] "E:/IRI Data/External/demo8.CSV"
[3] "E:/IRI Data/External/demos10.CSV"
[4] "E:/IRI Data/External/demos11.CSV"
[5] "E:/IRI Data/External/demos9.CSV"


Which has different font sizes for the .csv formats. I have the following function:



myfiles = lapply(myfiles,
FUN = function(files) {
read.csv(files, header = TRUE)
})


Which reads in the .csv files, however, I have some lowercase and some uppercase so I am running into errors on line 3 of that function read.csv - I am trying to expand the function such that if the file does not exits for .csv lowercase then try .CSV uppercase.



Any help would be great.

  • which of the files you want to read? Do you want to avoid reading the .csv files?

  • Ah sorry, I am trying to read all of the files using this function. For a similar task I read all of the .csv lowercase and it stores them as a large list of 5 elements.

  • Where is the issue in reading these files? Are you saying that 2:5 files are not reading

  • The issue is coming from the file extentions. The line read.csv(files, header = TRUE) is only able to read in lowercase .csv files so when an uppercase .csv file extention is thrown at it the function breaks.
