[Rd] file.copy() problems on WinNT (PR#1085)
For some files, file.copy() doesn't copy these files correctly.
Here you will find a file (Bitmap, 769Kb) to reproduce the problem:
http://www.statistik.uni-dortmund.de/leute/ligges/R/test1.bmp
Using
file.copy("c:/test1.bmp", "c:/test2.bmp", overwrite = TRUE)
produces a second file with the size of ~1.4 Mb:
http://www.statistik.uni-dortmund.de/leute/ligges/R/test2.bmp
To reduce size, I put both files into following zip archive:
http://www.statistik.uni-dortmund.de/leute/ligges/R/test.zip
Using file.copy() with the same file on Solaris and Linux works fine.

Looks like it is written to expect text files. Please try making the file opens in R_AppedFile binary, and tell us if that solves it.

Changing "a" to "ab" and "r" to "rb" in the following lines of R_AppendFile (file: /src/main/platform.c) solves the problem. if((fp1 = R_fopen(R_ExpandFileName(file1), "a")) == NULL) { return 0; } if((fp2 = R_fopen(R_ExpandFileName(file2), "r")) == NULL) { Thank you!
