...I do: > is.matrix(parcelas.cobtot.conti) [1] TRUE > dim(parcelas.cobtot.conti) [1] 25 64 > a <- data.frame(parcelas.cobtot.conti) > is.data.frame(a) [1] TRUE > > dim(a) [1] 1600 3 Why a does not have the same dimensions than parcelas.cobtot.conti? I've tested with caith and the behaviour there is different: > data(caith) > is.data.frame(caith) [1] TRUE > dim(caith) [1] 4 5 > a <- as.matrix(caith) > dim(a) [1] 4 5 > b <- data.frame(a) > dim(b) [1] 4 5 What can be wrong with parcelas.cobtot.conti ? I'd appreciate any help Thanks,...

...My question is about the substance of correspondence analysis. Specifically, is it appropriate to use ca on a matrix of values such that the columns and/or rows are not mutually exclusive? To be more detailed: - The standard use of ca is illustrated in the example of corresp() (from MASS): data(caith) library(mva) corresp(caith) biplot(corresp(caith, nf=2)) > caith fair red medium dark black blue 326 38 241 110 3 light 688 116 584 188 4 medium 343 84 909 412 26 dark 98 48 403 681 85 in this table, presumably, an observation can fall in only...

Playing around with examples from MASS4, I found a font problem in the mosaicplot in R-2.3.0. It doesn't happen in other plots. Running this example from MASS4, page 326... library(MASS) caith1 <- as.matrix(caith) names(dimnames(caith1)) <- c("eyes", "hair") mosaicplot(caith1, color = TRUE) ...I get an image as attached. The column and row labels are unreadable. It is true for both x11() and png() devices. I can adjust the font sizes with the "cex.axis&qu...

dear, I am trying to plot a standard plot, but I want the x axis to be 1,2,4,8,16 with equal intervals between them on plot. I will appreciate some help.
