[R] difference in order() between Linux and Windows with mixtures of caps and normal letters

[Joris DeWolf]

Could anybody explain this difference in the function order() between R 
under windows and R under Linux ?
It seems that under Linux the order in of character dsitinguishes 
between caps and normal letters and sorts them starting with the 
capitals (see below).
How can I avoid this (I mean: get the same results as I get under Windows)?
Thanks
Joris


Under Windows R 1.6.2

 > mstring <- c("b","c","a","t","d")
 > mstring[order(mstring)]
[1] "a" "b" "c" "d" "t"
 > Mstring <- c("b","c","a","T","D")
 > Mstring[order(Mstring)]
[1] "a" "b" "c" "D" "T"


the same under Linux R.1.6.2

 > mstring <- c("b","c","a","t","d")
 > mstring[order(mstring)]
[1] "a" "b" "c" "d" "t"
 > Mstring <- c("b","c","a","T","D")
 > Mstring[order(Mstring)]
[1] "D" "T" "a" "b" "c"
