Dear R-users, The following question bothered me for the whole afternoon: how can one pass a string as the conditioning argument to subset? I tried plain mystr, eval(mystr), expression(mystr), etc... I don't to be able to find the correct syntax > foo <- data.frame(a=1:10,b=10:1,c=rep(1:2,5)) > mystr<-"c==1" > subset(foo,c==1) a b c 1 1 10 1 3 3 8 1 5 5 6

I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3 a4 b1 b2 b3 c1 c2 d &...

HI, While I testing some code, I found some problem on Union handling. I've wrte following test code, and it has union assignment. The code's output is from pointerToUnion: chars mystring, length 64 from original: chars mystring, length 8000 It's caused by second char member(charlength) of LongestMember. For union assignment, llvm-backend seems generates assigning each member of largest union member. (I've checked it on llvm assembly level..) But sometimes there is padding...

Please consider following string: MyString <- "ABCFR34564IJVEOJC3434" Here you see that, there are 4 groups in above string. 1st and 3rd groups are for english letters and 2nd and 4th for numeric. Given a string, how can I separate out those 4 groups? Thanks for your time [[alternative HTML version deleted]]

Dear R-users, I need to dynamically recognize the index of a given string myStr in a vector of string. The problem is that myStr might contain parenthesis, causing grep not to recognize it the way I want (see below). The help mentions that the pattern used by grep should be in the POSIX format... I guess the problem is here; unfortunately, I am not familiar with the subtleties of the POSIX

Dear R-users, I am trying to use the grep function to test whether a particular string is of the form "n.../mydir/myfile.mytype.myext". Anything between n and mytype could vary, and anything after mytype could vary.

Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space!
