Hello,
I am a biologist and I am dealing with files composed of columns with T or A
or C or G (example below)
Sometimes a column is composed of only "T"
and in that case, the columns becomes a logical column TRUE (example below)
I know that the argument "as.is" controls the turns off turning a column
into a factor, instead becoming a character
Is there something similar for Iogical? (I could not find it)
I can solve this problem by doing something like:
#
FUN.changeLogi <- function(df){
if(identical(all.equal(all(df), T), T)) df <- 'T'
return(df)
}
xx <- do.call('cbind', lapply(xx, FUN.changeLogi))
but it seems very cumbersomeÂ…
Thanks,
Tiago Magalhães
produce a text file example.txt
A C A T C G F
A A C T C G F
A C A T C G F
A G A T C G F
T A C T C G F
xx <- read.table('example.txt')
str(xx)
xx <- read.table('~/Desktop/temp.txt')
$ V1: chr "A" "A" "A" "A" ...
$ V2: chr "C" "A" "C" "G" ...
$ V3: chr "A" "C" "A" "A" ...
$ V4: logi TRUE TRUE TRUE TRUE TRUE
$ V5: chr "C" "C" "C" "C" ...
$ V6: chr "G" "G" "G" "G" ...
$ V7: logi FALSE FALSE FALSE FALSE FALSE
