similar to: help with regexp

I have a list of suffixes I want to turn into file names with extensions. suff<- c("C1", "C2", "C3") paste("filename_", suff[[1]], ".ext", sep="") [1] "filename_C1.ext" How do I use lapply() on that call to paste()? What's the right way to do this: filenames <- lapply(suff, paste, ...) ? Can I have lapply()

Dear R users, the way I understand the documentation of sub() and regexp the following code: sub('[[:digit:]]{1,2}', '', '9ewww') ... should yield: 'ewww' It returns, however: 'www' Why is this the case? My code should just substitute 1 (minimum) or up to 2 (maximum) digits, i.e. numbers and not the 'e' in the string. Do I misinterpret

Hi all R users Ive got a file that contains diffrent settings in the manor of: setting1="value1" setting2="value2" setting3="value3" setting4="value4" . . . What I want to do is open the file and change the value of a specific setting like wanna change setting4="value4" -> setting4="value5" and then save the file again.

Thank you very much for your suggestions. That's very helpful. However, since I'm trying to compile several somewhat large projects, I assume generating bitcode for each single file and linking them together might be painful (I don't want to modify too much the project makefiles). So I hope my pass can be used just with simple compilation command like "llvm-gcc

hello, I want to use randomForest to classify a matrix which is 331030?42,the last column is class signal.I use ? Memebers.rf<-randomForest(class~.,data=Memebers,proximity=TRUE,mtry=6,ntree=200) which told me" the error is matrix(0,n,n) set too elements" then I use: Memebers.rf<-randomForest(class~.,data=Memebers,importance=TRUE,proximity=TRUE) which told me"the error is

Dear list, this might be an easy one, but I could figure out a solution (or how to google the right term). Is there any way to test whether all elements of a vector are identical? For numeric vectors I would use sum(diff(vector)==0)==0 but I have character vectors. Any Ideas? Cheers Jannis

Dear list members, is it possible to set some options only inside a function so that the original options are restored once the function is finished or aborted due to an error? Until now I do something like: dummy=function() { old.options=options(error=dummy1()) .... options(old.options) } This works for most cases but when the function terminates because of an error and its last

Dear list members, I frequently program small scripts and wrap them into functions to be able to check them with checkUsage. In case these functions (loaded via source or copy pasted to the R console) use functions from other packages, I get this error: no visible global function definition for ?xxxxxxx? For example: test = function() { require(plotrix) color.legend() }

Dear List, does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file. Any ideas? Jannis

Dears, a way to define x and y positions in plots in relative numbers (e.g in fractions between 0 and 1 referring to relative positions inside the plot region) would really help me. One example I would need this to would be to add text via text() to a plot always at a defined spot, e.g the upper left corner. Until now I always determined maximum x and y values and used those, but defining

Hi All, Do to popular request, I just set up a new mailing list to capture the nightly tester output from the various testers running 'round the world. The new list is available here: http://mail.cs.uiuc.edu/mailman/listinfo/llvm-testresults If you're running a nightly tester, please update your crontab to send mail to the llvm-testresults at cs.uiuc.edu list (potentially in addition

Okay, I'll have to fix NightlyTest.pl not to use shell script syntax that isn't universal. Look for a commit soon. Reid.

How should you map resources that are join models like Memberships? Lets say have you have Members and Groups that are joined through Memberships. map.resources :members do |members| members.resources :groups do |groups| groups.resources :memberships end end This doesn''t seem right. It would be nice to access all members, groups, and memberships at /members,

How do the llvm-gcc developers handle regression testing? Are there regular postings of the make check results for llvm-gcc-4.2 such as on the gcc-testresults mailing list? If not, it might be a good idea if linux and darwin workstations could be found to dedicate as regression test machines and a llvm-gcc-testresults mailing list created for those results. That would be extremely useful in

Hi everybody How do I do to calculate the median and average of a colum of time data like this: "8:50:10". I also need to plot the time difference between two colums Thanks a lot -- View this message in context: http://n4.nabble.com/median-for-time-data-tp932287p932287.html Sent from the R help mailing list archive at Nabble.com.

Dear R community, I have a general question regarding indexing in multidiemensional arrays. Imagine I have a three dimensional array and I only want to extract on vector along a single dimension from it: data <- array(rnorm(64),dim=c(4,4,4)) result <- data[1,1,] If I want to extract more than one of these vectors, it would now really help me to supply a logical matrix of the

Hi Bob, are these performance regressions real? They look pretty serious. Ciao, Duncan.

Dear list, is there a function in R that returns the product of a vector? E.g. if the vector is c(1,2,3,4) it should return 1*2*3*4=24 Cheers Jannis
