similar to: Just another ini patch

Hi, recently I took a look at ini to find a bug which made it crash at startup. While fixing the bug I realized I could do some improvements to the option reading code (espacally the action part). So I went on and here we are. This patch should make ini more robust, clean it up and fix also some more crashes I had here. Additionaly, I have a attached a second patch from Maniac which should fix

The ini plugin segfaults on startup. The following patch fixes it. Not sure why this hasn't been caught before - i guess not many people use the ini plugin.

Hi R mailing list, probably a very basic problem here, I try to do the following: > Q<-c(1,2,3) > P<-c(4,5,6) > A<- data.frame(Q,P) > A Q P 1 1 4 2 2 5 3 3 6 this is my simplified data.frame (matrix) now I try to create following loop for subtraction of element within the data.frame: > for(i in length(A[,"P"]-1){ delta[i]<-

Hi all, Is there a function to check if a particular value is contained in a vector? I've looked at grep in the hope that I could use a Perl-like syntax, but obviously it's different... I'd like to do something like: y <- c("a","b","c") if("a" in y) { # "a" is not in y } Also, is there a way to

Hi We have a Replica 2 + Arbiter Gluster setup with 3 nodes Server1, Server2 and Server3 where Server3 is the Arbiter node. There are several Gluster volumes ontop of that setup. They all look a bit like this: gluster volume info gv-tier1-vm-01 [...] Number of Bricks: 1 x (2 + 1) = 3 [...] Bricks: Brick1: Server1:/var/data/lv-vm-01 Brick2: Server2:/var/data/lv-vm-01 Brick3:

Hi all, Given a number of points (x,y) in a plane, I'd like to plot a map of polygons, so that 1) each polygon contains exactly one point 2) the polygon defines the area for which this specific point is closer than any other point. It's a bit like a map of areas "influenced" by that point, and it's obviously a matter of intersecting the perpendicular bisectors

Hi all, I am trying to produce some panels with dots in an X/Y plane where the diameter of the dots indicates a Z value (like e.g. earthquake maps where dot sizes indicate magnitudes and X/Y the location). This works fine with xyplot, e.g.: xyplot(1:3~1:3,cex=1:3,pch=16) However, when I do this with a panel variable, e.g.: x<-rep(1:3,5) y <- rep(1:3,5) sz <- rep(1:5,each=3) grp

Dear mailing list, I have following array: X2 Y2 [1,] 422.7900 6.0 [2,] 469.8007 10.5 [3,] 483.9428 11.0 [4,] 532.4917 25.5 [5,] 596.1942 33.5 [6,] 630.8496 40.5 [7,] 733.2996 45.0 [8,] 946.4779 32.0 [9,] 996.8068 35.5 [10,] 1074.3310 23.0 I do afterwards the following: plot.new() plot.window(xlim=c(min(X1)-50,max(X1)+50),

What's the logic behind the following, and where can I find any documentation about it? In particular, why are 2:9 - as characters - not regarded as being smaller than 10? # R-Code: a <- as.character(1:12) a < 10 # [1] TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE Thanks in advance!

Dear all, I am not sure if this mail is for R-help or should be sent to R-devel instead, and therefore post to both. While using nlrob from package 'robustbase', I ran into the following problem: For psi-functions that can become zero (e.g. psi.bisquare), weights in the internal call to nls can become zero. Example: d <- data.frame(x=1:5,y=c(2,3,5,10,9)) d.nlrob <-

Hi all, I ran into a problem in some of my code that could be traced back to 'mean' sometimes returning NA and sometimes NaN, depending on the value of na.rm: > mean(c()) [1] NA > mean(c(NA),na.rm=T) [1] NaN However, I don't understand the reasoning behind this and would appreciate and explanation. I understand that the mean of an empty vector is not definied, but I

Hi all, I wonder how to correctly write the following expression (it's the axis label in a plot command): ylab=expression(y' == y - bar(y) ) Somehow the single quote in y' is causing the problems, I guess because it is interpreted as a quote... Does it have to be escaped? But how? Thanks for your help Pascal

Greetings, I am struggling a bit with a non-linear regression. The problem is described below with the known values r and D inidcated. I tried to alter the start values but get always following error message: Error in nlsModel(formula, mf, start, wts): singular gradient matrix at initial parameter estimates Calls: nls -> switch -> nlsModel I might be missing something with regard to the

Hi all, I repeatedly encounter the following problem: After importing a data set into a data frame, I wish to set a column with numeric values to be a factor, but can't figure out how to do this. Also, I do not wish to write as.factor(x) all the time. I can create a new vector with x <- factor(x), but the new vector resides outside the attached data frame. Pascal > attach(ngrad)

Hi all, I am playing around with latin squares, and wrote a recursive function that searches for valid combinations. Apart from the fact that there are very many, I run into troubles beginning with size 10x10 because the recursion depth becomes too large (max of 10x9-1=89 in this case). Why is this a problem? Isn't there enough space allocated to the stack? Can this be increased? The

Hi, I just noticed that the current image loader plugins such as PNG, SVG and JPEG don't provide a feature as they used to do. This is needed for conflict checking and feature testing (e.g. by the settings manager). If I remember correctly this plugins had features before the metadata port so I did a patch to add them again. What do you think about that? Regards, Patrick -------------- next

Hi all, Thanks for the incredibly quick help with the "%in%"... There's a second question, though: I'd like to increment an element of a vector if a certain event occurs, e.g. count[event] <- count[event] + 1; # works, but... Is this efficient? I wonder whether R needs to subset the count vector on both sides of the assignment operator (i.e., twice), or

Hi all, is there an easy way to build up a data frame by sequentially adding individual rows? The data frame consists of numeric and character columns. I thought of rbind, but I ended up with numeric values for the character columns. Pascal

Hi all, I tried to save a complete log of a R session we had in a seminar today... but I didn't succeed. 1) R | tee session.log This saves both input and output, but I do get the cursor key escape sequences from editing (cursor-up to get last command etc) instead of the actual command line executed. 2) savehistory Gets commands only, not the output 3) sink Gets output, without the

I'm using nls to fit periodic gene-expression data to sine waves. I need to set the upper and lower boundaries, because I do not want any negative phase and amplitude solutions. This means that I have to use the "port" algorithm. The problem is, that depending on what start value I choose for phase, the fit works for some cases, but not for others. In the example below, the fit works
