Hi, So far as I can tell, the 'col.ticks' parameter for axis() only uses the first value provided. E.g.: plot(0:1,0:1, col.ticks=c('blue','red','green')) #all ticks are blue Just wondering if there's a different option in the basic plot commands that can handle multiple colors, and also whether ggplot and/or lattice allow for multiple tick colors.

This question attacked me as I was thinking about matrix value updates. I probably will never need to do this, but wanted to ask if there are efficient methods to perform the for-loop in the following sequence. %xymat<-matrix(rep(0,100) nr=10,nc=10) # empty matrix %x<-1:10 %y<-sample.int(10,10,rep=T) %for (j in 1:10) xymat[x[j],y[j]] <- some_function(x[j],y[j]) #to create either

Ok, so I'm slowly figuring out what a factor is, and was able to follow the related thread about finding a mode by using constructs like my_mode = as.numeric(names(table(x))[which.max(table(x))]) Now, suppose I want to keep looking for other modes? For example, Rgames> sample(seq(1,10),50,replace=TRUE)->bag Rgames> bag [1] 2 8 8 10 7 3 2 9 8 3 8 9 6 6 10 10 7 1

Hi, Here's the problem I ran into: the gmp package has a method for apply() so it masks the base::apply function. With gmp installed, I tried to run the function turnpoints() from the pastecs package. It fails because it calls apply() internally, like this: apply(mymatrix,1,max,na.rm=TRUE) , but the code in the gmp package which sets up the operator overload for apply() strictly

Dear list, I have been struggling for some time now with this code... I have this vector of unique ID "EID" of length 821 extracted from one of my dataframe (skate). It looks like this: > head(skate$EID) [1] "896-19" "895-8" "899-1" "899-5" "899-8" "895-7" I would like to remove the complete rows in another dataframe

Hi all, I'm working with a bunch of large graphs, and stumbled across something useful. Probably many of you know this, but I didn't and so others might benefit. Using pch="." speeds up plotting considerably over using symbols. > x <- runif(1000000) > y <- runif(1000000) > system.time(plot(x, y, pch=".")) user system elapsed 1.042 0.030 1.077

Greetings, I just upgraded my samba server to the latest Debian stable package, which is listed as: 2.2.3a-6. I got the following errors in the logs when a user installs a printer: barfoo smbd[1083]: [2002/08/30 10:36:12, 0] libsmb/cliconnect.c: attempt_netbios_session_request(977) barfoo smbd[1083]: attempt_netbios_session_request: FOOBAR rejected the session for name *SMBSERVER

Hello R-world! This is my first post to the R list, so I feel that I need to say thanks to the community (I'm using R now for 5 months)! I'd greatly appreciate if somebody could explain some odd behavior of ".Fortran" to me. Let's assume a primitive Fortran subroutine barfoo.f ---------------------------- subroutine bar(y, v) double precision y real v

Hi, While playing with quantile-quantile plots, I wrote up some code which plots something strangely different. Here's the pseudocode: testhist <- hist(sample_data) refhist <- hist(rnorm(n, mean=0,sd=1)) # for some large-ish n cumtest <- cumsum(testhist) cumref <- cumsum(refhist) plot(cumref,cumtest) This produces a straight line of slope 1 for a sample with the same

I followed a couple threads from the archives and from stackoverflow.com, and would like to know: just what is "..." ? What I mean by this is,for example, from the point of view of a user running a function in debug mode, is "..." an object, or does it exist in the current environment as some thingy? Maybe a better question to ask is: if I were to write some function

Hi all, I'd like to plot the Real and Imaginary parts of some f(z) as two different surfaces in wireframe (the row/column axes are the real and imag axes). I know I can do it by, roughly speaking, something like plotz <- expand.grid(x={range of Re(z)}, y={range of Im(z), groups=1:2) plotz$func<-c(Re(f(z),Im(f(z)) wireframe(func~x*y,data=plotz,groups=groups) But that seems like a

Hello there, while bash completion was working great to me in CentOS6, since I'm using C7 I spend my day stuck on completion not working the way it should. The bad situations I'm facing are: - it doesn't expand *foo whereas there are *foo-named files in current dir, for instance: # rm *foo will show nothing whereas there's a file barfoo in curdir. - completion takes 10

Hello, everybody! I have a matrix "input" (see example below) - with all unique entries that are actually unique ranks (i.e., start with 1, no ties). I want to assign a value of 100 to the first row of the column that contains the minimum (i.e., value of 1). Then, I want to assign a value of 100 to the second row of the column that contains the value of 2, etc. The results I am looking

Hello All, Moving from 2.5 to 2.6.2 and I was wondering if there is a preferred directory structure for using multiple environments? Does it work much different in 2.6 than in 2.5? When I made the move I assumed (I know) that my current structure and configurations would just roll over but that isn''t the case.

Hi, I would like to produce a plot with a symbol on every nth point in a time series data, like the one in the following: http://www.phon.ucl.ac.uk/home/yi/ProsodyPro/EnglishFocus.png x <- seq(-100,1000,25) plot(x,type="l") Could someone help me out with the above example?
