Dear all, if gray is the background collor of a trellis xyplot (in the lattice library) and I would like to switch to white, what I have to do? Why dark gray was chosen as the default color? Many thanks...

Dear all, I am trying to compute a matrix of Pearson's `r' or Spearman's `rho' rank correlation coefficients using rcorr (Hmisc) the following way: > mx<-rcorr(x, type="spearman")[1] but then ... > is.matrix(mx) [1] FALSE Even...

Dear all, I am working with a matrix structured as follows Factor 1 Factor2 ... Country 1 Country 1 Country 2 Country 2 ... Country N Country N and I need to rearrange it according to the following scheme Factor 1 Factor2...

Dear all, in package Hmisc `rcorr' computes a matrix of Spearman's `rho' rank correlation coefficients for all possible pairs of columns of a matrix. What if I want a matrix of rank correlation coefficients for pair of columns of...

Dear R-friends, in plotting x and y, conditioning on z, I am trying to find a way to make the standard errors appearing together with the loess in the trellis plot. I have tried the following code without success...
