Dear R-users, The strsplit function does not exist in S-plus and I would like to use it. How could I reproduce the function in Splus or access to its source code? Thank you in advance, Sebastien

can someone show me how to use a regular expression to break the string at the bottom up into its three components : (-0.791,-0.263] (-38,-1.24] (0.96,2.43] I tried to use strplit because of my regexpitis ( it's not curable. i've been to many doctors all over NYC. they tell me there's no cure ) but it doesn't work because there also dots inside the brackets. Thanks. (-0.791,-0.263].(-38,-1.24].(0.96,2.43]

Hello, I would like to know what can I do if I use strplit with a string and I want to use the middle left,I mean I have this: strsplit("bA531F16-rep","\\-") [[1]] [1] "bA531F16" "rep" I would like to work just with bA531F16 in another variable, what could I do?, Thank you -----------------...

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ... I would like to turn this dataframe to station substation time data A1 B1 t1...

I'm having an odd problem with strsplit (well I think it's strplit that's causing the problem). When I run the code below as follows: str(parseFormulaMin(y +x +d ~ b +d +e| a * b)) I expect to get List of 3 $ y: chr "y+x+d" $ x: chr "b+d+e" $ g: chr "a*b" But about half the time I get List of 3 $ y: chr "y+x+d"...

Hi all, I have read posts of heat map creation but I am one step prior -- Here is what I am trying to do and wonder if you have any tips? We are trying to map sequence reads from tumors to viral genomes. Example input file : 111 abc 111 sdf 111 xyz 1079 abc 1079 xyz 1079 xyz 5576 abc 5576 sdf 5576 sdf How may xyz's are there for 1079 and 111? How many abc's, etc?

Hi all, is there any function to find some words in a character-string? For example suppose the string is : "gdfsa-sdhchc-88", now I want to find whether this string contains "sdhch". Is there any R function to do that? Regards, -- View this message in context: http://www.nabble.com/Searching-within-a-ch.-string-tp23484010p23484010.html Sent from the R help mailing list

Hi, I find this behavior unexpected: --8<---------------cut here---------------start------------->8--- > strsplit(c("a,b;c","d;e,f"),c(",",";")) [[1]] [1] "a" "b;c" [[2]] [1] "d" "e,f" --8<---------------cut here---------------end--------------->8--- I thought that it should be identical to this:

...run into several related problems. As you all know, grep and regexpr will only give me the first hit anyway - which is how I identified the lines in the first place - but for the desired output I need all the hits per line together with their context. But, obviously, when I split up the line using strplit and "<w " as a separator so that I can get all hits and all words for the columns -3 to -1 and 1 to 3, the expression matched by the search string b is also split up and cannot be put into one tab-separated central column anymore and I don't seem to be able to extract all hits to s...

Hi all, I'm a beginner user of R. I am stuck at what I thought was a very obvious problem, but surprisingly, I havent found any solution on the forum or online till now. My problem is simple. I have a file which has entries like the following: #ID Value1 List_of_values ID1 0.342 0.01,1.2,0,0.323,0.67 ID2 0.010 0.987,0.056,1.3,1.5,0.4

Bottom Line Up Front: How does one reshape genetic data from long to wide? I currently have a lot of data. About 180 individuals (some probands/patients, some parents, rare siblings) and SNP data from 6000 loci on each. The standard formats seem to be something along the lines of Famid, pid, fatid, motid, affected, sex, locus1Allele1, locus1Allele2, locus2Allele1, locus2Allele2, etc In other

All, I have some csv files I am trying to import. I am finding that quotes inside strings are escaped in a way R doesn't expect for csv files. The problem only seems to rear its ugly head when there are an uneven number of internal quotes. I'll try to recreate the problem: # set up a matrix, using escape-quote as the internal double quote mark. x <-
