Hi, I am trying to list all the sub-directories in a particular directory and having a few issues. list.dirs seems to be slightly broken and/or poorly labelled. My issue appears to be the same as this one, from the archives:
http://tolstoy.newcastle.edu.au/R/e16/help/11/11/1156.html Here is some of my current platform info: R version 2.15.0 (2012-03-30) Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit) RStudio Version 0.95.263 Setting the full.names argument to FALSE simply doesn't appear to work. To get the desired behavior, I have to wrap the entire command in basename(), as in the final example. BTW, I've truncated to output in width and length for the sake of brevity. > getwd() [1] "/Users/name/Documents/R" > list.dirs(full.names = FALSE, recursive = FALSE) [1] "./abc" "./bcd" "./cde" "./data1" > list.dirs(".", full.names = FALSE, recursive = FALSE) [1] "./abc" "./bcd" "./cde" "./data1" > list.dirs("./", full.names = FALSE, recursive = FALSE) [1] ".//abc" ".//bcd" ".//cde" ".//data1" > list.dirs("data1/SP", full.names = FALSE, recursive = FALSE) [1] "data1/SP/2010-01-29" "data1/SP/2010-12-13" "data1/SP/2010-12-31" [7] "data1/SP/2011-01-06" "data1/SP/2011-01-07" "data1/SP/2011-01-10" [13] "data1/SP/2011-01-14" "data1/SP/2011-01-18" "data1/SP/2011-01-19" [19] "data1/SP/2011-01-25" "data1/SP/2011-01-26" "data1/SP/2011-01-27" > list.dirs("data/SP", full.names = TRUE, recursive = FALSE) [1] "data1/SP/2010-01-29" "data1/SP/2010-12-13" "data1/SP/2010-12-31" [7] "data1/SP/2011-01-06" "data1/SP/2011-01-07" "data1/SP/2011-01-10" [13] "data1/SP/2011-01-14" "data1/SP/2011-01-18" "data1/SP/2011-01-19" [19] "data1/SP/2011-01-25" "data1/SP/2011-01-26" "data1/SP/2011-01-27" > basename(list.dirs("data1/SP", full.names = FALSE, recursive = FALSE)) [1] "2010-01-29" "2010-12-13" "2010-12-31" "2011-01-03" "2011-01-04" [11] "2011-01-12" "2011-01-13" "2011-01-14" "2011-01-18" "2011-01-19" [21] "2011-01-27" "2011-01-28" "2011-01-31" "2011-02-01" "2011-02-02" [31] "2011-02-10" "2011-02-11" "2011-02-14" "2011-02-15" "2011-02-16" Is the full.names argument broken, and what is it supposed to do? Even as it currently is, I wouldn't exactly describe the outputted pathnames as "full", more accurately as "relative pathnames" from the current working directory. Does anyone know if list.dirs is really broken or if this is the desired behavior?
