similar to: Windows list of Folders

For windows, how can I list only the folders in some folder? I was thinking that dir() and file.info() with isdir==TRUE being something that might work. These folders or directories are numerically named with no dot extension names or other characters. Typically, these are 3132, 3334, ... Here is what I tried. The last line is where I need more work. pData="C:/Myfiles/R/Data/" setwd

How can I stop the following warning from occuring? invalid factor level, NAs generated in: "[<-.factor"(`*tmp*`, iseq, value = structure(1, .Label = "12", class = "factor")) The Label messages are for "5", "8", "12" and "46". I want the NAs to be generated as needed. Is this causing R to slow down by generating the warning

I have a general question. Is there a setting that can be used for a multiple line type? The situation is that I want a solid line between x and y points but if the y point is missing, I want a dashed line type to the next point. In other words, if point 1 to 2 exists, make that line solid, otherwise, make it dashed up to the next existing x/y point. Additionally, what plot type would you

Is there anyway to preset date formats? I have a date from a cover.dbf that is shown as this: > cover$FINALREPOR [1] "2003-06-24" The numeric value in cover$FINALREPOR is 12227. I'd rather not create another vector to hold the properly formatted date. When I put this in a WordPerfect merge, I want the date to be June 24, 2003. I could take care of the problem in a

I am using rbind to add one list with one row to another master list. The problem is that not all columns exist in both lists. What methods would you recommend to reorder one list based on the column names of another? If both sets have the same order and columns, I can then use rbind. I can live with columns being added to the master list set it makes the task easier using something like

In this simple function, how can I pass strings for index and column names to the function? I've posted this type of question before and received no response. Maybe this example will be easier to understand and troubleshoot. ds <- function(myds, vec) {myds[[vec]]*2} ds1 <- c(X=list(1:10), Y=list(11:20)) ds(get("ds1"),get("Y")) khobson at odot.org Kenneth Ray

I am a new user of R so please bear with me. I have reviewed some R books, FAQs and such but the volume of material is great. I am in the process of porting my current SAS and SVS Script code to Lotus Approach, R and WordPerfect. My question is, can you help me determine the best R method to implement the Hoaglin Outlier Method? It is used in the Appendix A and B of the fo llowing link.

Please allow me an unusual question. Is there any way that R can be closely integrated with a Microsoft Powerpoint presentation? I would like to embed R calculations in Powerpoint so that I will start Powerpoint, be prompted to enter some parameters, and an R function will run and return values and graphs. Thanks, John R 2.1.1 windows 2k John Sorkin M.D., Ph.D. Chief, Biostatistics and

I use R to generate data and I need to estimate the data by egarch (that doesn't have in R). So how I can call egarch from SAS in R. Regards, luck

I write a function to get the frequency and prop of a variable. freq<-function(x,digits=3) {naa<-is.na(x) nas<-sum(naa) if (any(naa)) x<-x[!naa] n<-length(x) ta<-table(x) prop<-prop.table(ta)*100 res<-rbind(ta,prop) rownames(res)<-c("Freq","Prop") cat("Missing value(s) are",nas,".\n") cat("Valid case(s)

I wish to find any NA's in column's 1 or 3 and change the numerical value to the right of the " NA"'s . In this case I

Hi, I was playing around with inotifywait (great tool!) to see the new staged installation of source packages in action. In one terminal I'm monitoring the create/delete/move events of the installation library with: ? inotifywait -m --timefmt '%F %T' --format '%T -- %w %e %f' -e create -e delete -e move path/to/R/library/ While in another terminal I install CRAN package

Compiling this little function gets me some strange behaviour .initDataDir <- function(){ if(file.exists(LOCATION)) { if(as.logical(file.info(LOCATION)["isdir"]))return stop(LOCATION, " exists but is not a directory") } Z <- dir.create(LOCATION) if(!Z){ stop(geterrmessage()) ## stop("Juggel") } return(Z) } > .initDataDir <-

Hi, on Windows 7 (tested on NTFS file system) and R-devel: 1. file.info("C:/") gives NAs whilst file.exists("C:/") gives TRUE. Instead you have to do file.info("C:/."). 2. Any number of dots will do, e.g. identical(file.info("C:/........."), file.info("C:/.")) == TRUE DETAILS: # C:/ => DISCREPANCY file.exists() and file.info() >

Henrik, modTime.fromWin32Time(ftLastWriteTime); Note that you'll need write a "fromWin32Time" for the TimeValue class to make the conversion of ftLastWriteTime to TimeValue's notion of normalized time. isDir = dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY; fileSize = nFileSizeLow + (nFileSizeHigh << sizeof(DWORD)*8); The mode, user, and group fields aren't
