...t(col.whitebg()) is not used. The conclusion was that in the lset(col.whitebg()) environment, log(0) was not properly handled (leading to an error message or something else). I can provide a data.frame off the list to anybody who wants a reproducible example and to look at what happens.

...st copy a blank then. This does not occur with the classical plot(). Thus, I suppose that it may come from lattice or grid (going through the R-archives I checked that a similar trouble occur when R has been updated to 1.5). Has this trouble been met already and is there a way to turn it? Patrick Giraudoux

Dear listers, I have written a function to facilitate the drawing of altitude profiles with x (distance), y (altitude) and a z parameter (altitude magnification). profplot<-function(x,y,z=10,...){ op <- par()$mai par(mai=c(0.95625,0.76875,0.76875,0.95625)) plot(x,y*z, type="l",asp=1,las=1,xlab="",ylab="",yaxt="n",...)

Is there a fonction for multiple comparison tests (similar to "multicomp" in Splus) in a package of R? Thanks in advance for any hint...

Hi, I cannot go through the archives with which() as key-word... so common. Though I am sure to have seen something about this subject in the past could somebody put me on the track. I have a matrix (actually a data.frame) in which I would replace the non-null values by 1. I tried the following: indices<-which(myforetbin > 0,arr.ind=T) myforetbin[indices[,1],indices[,2]]<-1 and get

Folks, I have got a strange behaviour when testing this: sum(x) != 1 let us set x<-c(70,134,1,5,0) and transform it in a vector of probabilities x<-x/sum(x) One expect sum(x) should be equal to 1, which is apparently the case > sum(x) [1] 1 However, when I try to test it I get: > if(sum(x) !=1) print("lost") else ("OK") [1] "lost" Which means

Hi, I am trying to convert a data.frame of numerics (this could be a matrix as well in this case) into a data.frame of factors. I did it in a way that is less than direct... myforet2<-t(myforet) for (i in 1:length(myforet2[1,])) { if (i == 1)myforetfact<-list(as.factor(myforet2[,i])) else myforetfact<-c(myforetfact,list(as.factor(myforet2[,i]))) }

Hello, It seems that, unlike Splus, the anova.lm function of R does not take the argument ssType=3 into account. How can one get an anova table with the adjusted sum of squares in R?
