Error in FUN(X[[i]], ...) : subscript out of bounds

[csgillespie]

I've launched R in a directory with an empty .Rprofile and an .Renviron with the single line

R_LIBS=/data/ncsg3/Rpackages/

Launching R, I then get

ncsg3@jetset:/tmp$ R
> library(fs)
> dir_ls()
Error in FUN(X[[i]], ...) : subscript out of bounds

If I make the .Renviron empty, then everything works

ncsg3@jetset:/tmp$ R
> library(fs, lib.loc = "/data/ncsg3/Rpackages/")
> dir_ls()
RtmpJjQpb6

Could you provide the traceback for the error?

[csgillespie]

Different computer, but similar set-up in terms of OS.

> traceback()
7: vapply(nms, `[[`, character(1), 1)
6: setNames(vapply(nms, `[[`, character(1), 2), vapply(nms, `[[`, 
       character(1), 1))
5: colourise_fs_path(x, ...)
4: multicol(colourise_fs_path(x, ...))
3: cat(multicol(colourise_fs_path(x, ...)), sep = "")
2: print.fs_path(x)
1: function (x, ...) 
   UseMethod("print")(x)

Interestingly, this works

R> fs::dir_ls() %>% paste()
[1] "tmp1" "tmp2"
R> fs::dir_ls()
Error in FUN(X[[i]], ...) : subscript out of bounds

Something seems wrong in how your LS_COLORS environment variable is defined, could you give the value of that?

[csgillespie]

R> Sys.getenv("LS_COLORS")
[1] ":di=1;38;5;39:ex=1;38;5;34:ln=1;38;5;45:*.py=1;38;5;220:*.pdf=1;38;5;202:*.tex=1;38;5;196"

If you remove the leading : it should work.
