what about using "mapply"? splitted.value<-with(x.1, split(VALUE, GROUP)) splitted.freq<-with(x.1, split(FREQUENCY, GROUP)) mapply(weighted.mean, splitted.value, w=splitted.freq) Stefano >-----Messaggio originale----- >Da: r-help-bounces at stat.math.ethz.ch >[mailto:r-help-bounces at stat.math.ethz.ch]Per conto di >james.holtman at convergys.com

Thanks a lot, James!! The problem is fixed. On the version 1.4.0 Mac/darwin (the latest available version for this system) the function read.table (which is called from read.delim etc., too) has the bug you explained. Inserting the row nlines <- nlines+1 after lines <- c(lines, line) removes this bug. M. On Friday, February 22, 2002, at 02:33 PM, james.holtman at convergys.com

James, thanks for the response. I understand now my puzzle. tmp <- data.frame(y1=1:4, f1=factor(c("A", "B", "C", "D"))) tmp$y2 <- NA tmp[1:2, "y2"] <- 2 Does the job. I see that I should add a full column. In my case adding full column of NAs and then adding values, solves my problems. Thanks to all. james.holtman at convergys.com

I generated a PDF output file of 10 plots. When I try to view it with Adobe reader (R4 & R5), it will lockup the reader (it is consuming 100% of the CPU) after presenting the 4th plot. I can generate the plots just fine in Windows and as a postscript file reading it with GSview. Is there anyway to tell what might be wrong with the PDF output? The file is 890KB in size if anyone would like

The following script works fine in R 1.9.1. It was creating a PDF file with the graphs in it. In R 2.0.0, I got the error message below. I tried the same script just outputting to Windows and postscript and the output was OK. The error message only showed up when trying to create a PDF file. > version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386,

Dear R users and Helpers I am beginner with using R and interested in carrying out certain task for my statistical research. I am reading data for a text file, which could contain data in following pattern x y 8 10 11 14 16 16 18 15 6 20 4 4 20 18 As per the example I have two columns and 7 rows of data in each. However is real life data situation I may not know how many columns are present

I was using 'object.size' to see how much memory a list was taking up. After executing the command, I had thought that my computer had locked up. After further testing, I determined that it was taking 241 seconds for object.size to return a value. I did notice in the release notes that 'object.size' did take longer when the list contained character vectors. Is the time that it is

Dear Aki, i think I got it. Many thanks. it has to do with the permission settings.

drwx-----x kunal kunal Storage I'm guessing this point is being more restrictive. Can you try changing this into 0755? Also suddenly you are no longer using vmail but random user IDs. This only works with vmail. Aki > On 25 February 2019 19:56 Kunal A. <kunal.oa at gmail.com> wrote: > > > Hi, > Yes. Output ;- > > dr-xr-xr-x root root / > drwxr-xr-x root

Hey Aki, Sorry for the trouble but I am still unable to get it working. The file permissions for upper files are now drwxr-xr-x. but I think they need to be drwxr-x--x+ ? Any idea how to change it to that? Error log is below:- doveadm(lightdm): Error: Can't open mailbox Storage/Email: stat(/run/media/computer/Storage/Email/tmp) failed: Permission denied (euid=976(lightdm) egid=976(lightdm)

When I try to print out the refman.pdf file of version 1.3.0 to an HP LaserJet 8000 PS printer, I get the error message "Error occurred while downloading a font.

Anyone have luck with pxechn32 and bootmgfw.efi? I'm getting the "Unable to retrieve first package" issue as reported by others. Really, any advice for UEFI booting into a winpe environment off of pxelinux 6.03 would be beneficial.

Dear Aki, I have given permission to the folders Storage/Email to vmail. But the upper hierarchy is not under vmail . Full directory = /run/media/computer/Storage/Email /run/media/computer = not vmail Storage/Email = vmail How do I get this corrected ? It seems like vmail needs access through all through run/media/computer . Please excuse my ignorance as I am not very familiar with

I am trying to put some text data in a graphical output file so that I have a single file with both the graphs and summary data. I was capturing the output via a 'sink(textConnection('output','w')). This seems to work fine, but in trying to put the text data in a graphics frame, I was having problems. When creating a postscript file, things were fine, but a PDF file appeared

I was trying to print out some text on an empty PDF graph so that I would have the statistical data in the same file as the graphs. I was having problems in getting the output in a PDF file, but could get it in a postscript and BMP file. I put together the script below to see what 'fonts' were available on PDF, is it caused an exception. I was getting an exception in the pdf call
