Using concat.split on data containing an apostrophe causes error
IrwinKwan opened this issue · comments
concat.split doesn't appear to like apostrophes in the data column.
> df <- data.frame(experience=c("Did Use, Didn't like"))
> df
experience
1 Did Use, Didn't like
> concat.split(df, 1)
Error in FUN(NA_integer_[[1L]], ...) :
argument must be coercible to non-negative integer
If you try it without, it works fine.
I installed it from the package manager, appears to be v1.2.0.
Mac OS X x64, Mavericks
R 3.0.2
@IrwinKwan, thanks for the reproducible report. It seems to be because of the use of read.table
without the "quote
" argument.
read.table(text = as.character(df$experience), header = FALSE, sep = ",")
# [1] V1 V2
# <0 rows> (or 0-length row.names)
But:
read.table(text = as.character(df$experience), header = FALSE, sep = ",", quote="")
# V1 V2
# 1 Did Use Didn't like
I'll see what can be done to fix this quickly. It may be that just adding the quote = ""
to the functions would be sufficient, but I will need to test it on a few more cases.
Resolved by converting concat.split
to use cSplit
instead of read.concat
