OK this is bound to be something silly as I'm completely new to R - having started using it yesterday. However I am already warming to its lack of 'proper' GUI... I like being able to rerun a command by editing one parameter easily... try and do that in a Excel Chart Wizzard! I eventually want to use it to analyse some chemotherapy response / survival data. That data will not be

Dear R Users, I am a novice learner of R software. I am working with Genetic Matching - GenMatch(), but I am getting an Error message as follows:  Error in GenMatch(Tr = Tr, X = X.binarynp, BalanceMatrix = BalanceMatrix.binarynp,  :    GenMatch(): input includes NAs Could you please suggest me correcting the above problem? My GenMatch command is, > gen1 <- GenMatch(Tr = Tr, X =

To anyone who uses the Match() function in the Matching library... How do you go about deciding how many matches you will use? With my data, my standard errors generally get smaller if I use more matches. Speaking of standard errors, when correcting for heteroscedasticity, how many matches do you use (this is the Var.cal option). It seems to me that it might make sense to use the same number

Hello, I have a question as to how the syntax for glht(package multcomp) and estimable (gmodels) works, since I'm not getting everything from the documents I've googled so far, especially with models with 2nd order terms. A modestly complex model: 2-way anova with one continuous covariate, no random effects(and no repeated measures) to keep it modestly complex: Y = treatmentgroup + sex

Hello! If I understand this listserve correctly, I can email this address to get help when I am struggling with code. If this is inaccurate, please let me know, and I will unsubscribe. I have been struggling with the same error message for a while, and I can't seem to get past it. Here is the issue: I am using a data set that uses -1:-9 to indicate various kinds of missing data. I changed

Hi all, I am trying to create a "index.csv" with caliculating different types of caliculations . In that i have to caliculate on 10,000 studies and have to insert many no of rows more than 500,000 for that right now I am inserting every row after caliculating and doing data.frame but its taking much time to create that index.csv is there any thing like bulk insert in to file

I want to create a data.frame of time and date for a year. I started with the idea of simply producing two vectors (time and date) The first part ( time) is easy. rep(1:24, 365) But how do I get a series of 24 dates for O1 January 2005 and repeat this to 31 December 2005. It should be easy but I don't see it. Thanks

Hi All, I think i'm failing to undersatnd how aggregate() is supposed to work. example: test1<-sample(c(0,1),100,replace=T) test2<-sample(letters,100,replace=T) aggregate(test1,list(test2),sum) Error in data.frame(w, lapply(y, unlist, use.names = FALSE)) : arguments imply differing number of rows: 26, 0 I thought this would give me a list containing the number of ones that

Dear list, I would like to export a matrix to a TXT-File by using write.csv (not necessarily). Is there a way to add a header (with additional informations concerning the project) spanning multiple lines to this file before the actual data are listed up? Should look like this: date: filename: number of permutations: ------------ data (as a matrix) Any suggestions? Thnx in advance.

Hi all, Im a little bit confused concerning the effect() command, effects package. I have done several glm models with family=quasipoisson: model <-glm(Y~X+Q+Z,family=quasipoisson) and then used results.effects <-effect("X",model,se=TRUE) to get the "adjusted means". I am aware about the debate concerning adjusted means, but you guys just have to trust me - it

Hi all, Reading the wikipedia page on R, I stumbled across the following: http://fluff.info/blog/arch/00000172.htm It does seem interesting that the C execution is that much slower from R than from a native C program. Could any of the more technically knowledgeable people explain why this is so? The author also have some thought-provoking opinions on R being no-good and that you should write

Hi all, I'm currently preparing some figures that will be submitted to PloS One. In their guidelines they state that they will only accept figures in tiff or eps format, with the warning that eps figures will be converted to tiff format ( see http://www.plosone.org/static/figureGuidelines.action ). Because of this conversion, I figured I'd generate tiff-format figures from the beginning.

Dear all, Is there a way to generate K numbers of integer (K = 10^6). The maximum value of the integer is 200,000 and minimum is 1. And the occurrences of this integer follows a lognormal distribution. - Gundala Viswanath Jakarta - Indonesia

Yes, good point. I added the checking of prev_mode for Silk DTX to avoid using stale data from the Silk state. The PR is updated, and I'm attaching an updated patch. /Gustaf On Tue, 9 Apr 2019 at 12:42, Mark Harris <mark.hsj at gmail.com> wrote: > On 2019-04-08 4:55, Gustaf Ullberg wrote: > > Thank you Mark. > > > > I agree and have now updated the pull request

Hi all, I'm trying to download a file from the net, and the download.file command leaves it corrupted, i.e excel cannot open it. It seems as if it's going ok, however.

Hi all, I wonder if there is any way to calculate a moving average on an irregular time series, or use the rollapply function in zoo? I have a set of dates where I want to check if there has been an event 14 days prior to each time point in order to mark these timepoints for removal, and can't figure out a good way to do it. Many thanks in advance! Gustaf Example data:
