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

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

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]]

Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

..."Comment your code. Entire commented lines should begin with # and one space. Short comments can be placed after code preceded by two spaces, #, and then one space. " Just wondering if there is no way to comment something out "in the middle" of a line? Example: Original code: mystrings<-c("a","b","c") Desired commented code: mystrings<-c("a", # want "b" to be commented out, but not "c" # "c") So that it is read as: mystrings<-c("a","c") Not possible? Thanks! -- Dimitri Liakhovit...

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

I am doing controller testing, and I can''t seem to get the create method test to pass when friendly_id is added to the mix. If I comment it out of the model, the tests all pass perfectly. The moment I add it back in, the error looks like this: 1) Error: test_create_valid(BrandsControllerTest): FriendlyId::BlankError: FriendlyId::BlankError

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. I tried to proceed by steps to build my regular expression... but I do not really understand why the last call of the following code do not work. Any help would be

Hi, Is there an easy way to test if a substring exists in a string? I''m using this check: if mystring.index(substring) > 0 but it doesn''t seem to be working.... Thanks! -- Posted via http://www.ruby-forum.com/.

I have a matching problem that I cant solve. mystring = "xxx{XX}yy{YYY}zzz{Z}" where "x","X","y","Y","z","Z" basiclly can be anything, letters, digits etc. I'm only interested in the content within each "{}". I am close but not really there yet. library(gsubfn) strapply(mystring,"\\{[^\\}]+",, perl=F)

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! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab
