Hi! The postscript device in 0.90 does not produce symbols (pch=) as it should. E.g.: postscript(file="test.ps",width=8,height=6.4,horizontal=FALSE) plot(1:10,1:10,pch=1:5) legend(1,9,letters[1:5],pch=1:5) dev.off() The result looks quite different compared to the X-windows version. The symbol 1 (pch=1) is much to small, while the other symbols seem to big. Is it a bug? How can I

Dear R-List, I have a dataframe X containing factor f and numeric variable x1, x2, ... I want to create a new dataframe (or possibly a matrix) that gives statistics (e.g. sum) for the variables x1, x2, ... in each group defined by factor f. What is the simplest way to do this? I tried: attach(X) Z <- data.frame(f=levels(f),x1=as.vector(lapply(split(x1,f),sum))) and stumbled on: Error

Hi! Since installation of R 0.90 there are problems with the size of text and numbers also in the x11-device (I reported about similar problems with the postscript device recently). For numbers and letters a different size is used: plot(1:10,1:10,type="n") text(2,8,"F5F5F5F5F5") text(2,7,"F5F5F5F5F5",cex=2) The same problem is also found in the postscript

Hello! When I know the vector of the variance of the disturbances (i.e. the structure of heteroskedasticity), say Var(u_{i})=v_{i}, what is the weights I should use as argument to lm(): M <- lm(y~x,weigths=1/v) or M <- lm(y~x,weights=1/(v^0.5)) ??? In the help pages I did not find a clear answer to this question, so please could someone help me! Thanks, Wolfgang Koller

Dear R-developpers, currently the function window shows the following behaviour, if start or end is out of range: > x <- ts(1:14,start=c(1950,2),frequency=4) > y <- window(x,start=c(1950,1),end=c(1953,4)) Warning messages: 1: start value not changed in: window.default(x, ...) 2: end value not changed in: window.default(x, ...) Instead of this I would like it to fill with NAs the

I get John's value (48.8789) in 2.7.0 and R-devel (both on Ubuntu).
