It's often difficult to figure out what a problem data set looks like when someone pastes a mess of output from R into an e-mail. The dput command, used judiciously?I would hope no one would send a 1 M data set?can make life much easier. I wonder if it would be useful to add a hint in the instructions at the bottom of the posting page, where the list asks for self-contained reproducible

Hi, I'm trying to create an abbreviated data file from a larger version. I can use the subset command to create a value for this data: dat <-subset(raw.data, select=c(SNP, Pvalue)) > head (dat) SNP Pvalue 1 rs11 0.6516 2 rs12 0.3311 3 rs13 0.5615 but when I try to write.table using: write.table (dat, file = "/path/to/my/data.txt", sep = " ",

Dear R-users, I'm writing a program that constructs a dataset. I wish to save the dataset to a file. Here's a very simple example of what I'm trying to do function(x=peter){ y <- x/2 write.csv(y, file = "...\x") } The problem is that I want to name the dataset as whatever the name of the input is. In this case peter. How do I do this? Thank you in advance. Kristian

Hi all I am analyzing bird song element sequences. I would like to know how can I get how many times a given subsequence is found in single string sequence. For example: If I have this single sequence: ABCABAABABABCAB I am looking for the subsequence "ABC". Want I need to get here is that the subsequence is found twice. Any idea how can I do this? Thanks

I have a data frame 'tmp' and a vector 'name' containing 'd2'. I want to save 'tmp' under the name hidden in 'name', and the file must have the same name, plus the extension '.rda'. So I try > tmp x y 1 1 3 2 2 4 > name [1] "d2" > assign(name, tmp) > summary(get(name)) x y Min. :1.00 Min. :3.00 1st

I have a dataframe object having the following structure FinalOutput[1:3,] GasDays 2011-03-31 2010-09-30 2010-10-31 2010-11-30 2010-12-31 2011-01-31 2011-02-28 1 2006-10-01 217303553 221205033 222824639 217016511 216093460 216477468 216834021 2 2006-10-02 231158527 234565250 236004109 231467851 230100639 230079907 230734064 3 2006-10-03 282062314 285427832 286372163

I want to write a function that get 2 strings y and z and does the following R command. temp<-qq1[qq1$z==y,] for example if it get y="AMI" and z="PrimaryConditionGroup" It should do the following temp<-qq1[qq1$PrimaryConditionGroup=="AMI",] I could do it by the following function that is ugly and I wonder if there is an easier way to do it espacielly when temp
