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

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

Dear R developers, as far as I understand the manual of list.files(), there is only a way to exclude directories from the returned vector if you use list.files recursively. In non recursive mode, there seems to be no way of excluding directories (the include dirs argument does not seem to have any effect). Would it not be more intuitive and practical to allow the switching off of directory
