...few eigenpairs are needed : did somebody already care about this problem (through a contributed package for example) ? Or do I have to directly try to mess around with the LAPACK library (and contribute the package myself afterwards) ?

...")), vp=vp1) (I know I could do this in a simpler way, but let's suppose I want to go through the pushviewport / viewport def / grid.rect with vp argument sequence) I must be missing something obvious !

Dear All,   any thoughts on how I can do the following:   let us say we have:   a <-c(2,4,16,28,48) b <-c(10,4,2,0.4,0.03) d <-cbind(a,b)   what I would like to do is to extract values of column b in the matrix based on the corresponding values of column a. For example: I would like to extract all b values that have a corresponding a value that is less than 24 into a numeric vector, so

Good day. I create a data frame like this: > data <- data.frame(a=1:10,b=11:20,c=21:30) I can subset this data.frame by saying: > data[data$a>7,] and I get this result a b c 8 8 18 28 9 9 19 29 10 10 20 30 I understand I should get the same result by saying

Hi all. I would like to highlight overlapping regions of two densities and I could not find a way to do it. Here is the sample code: myd <- c(2,4,5, 4,3,2,2,3,3,3,2,3,3,4,2,4,3,3,3,2,2.5, 2, 3,3, 2.3, 3, 3, 2, 3) myd1 <- myd-2 plot(range(density(myd)$x, density(myd1)$x), range(density(myd)$y, density(myd1)$y), type = "n") lines(density(myd), col=1, lwd=4)
