Hello all, I posted a question some days ago without getting any answers, perhaps, as one of you kindly pointed out, because the question was not clearly stated. Let me reformulate it: In a frame, a column named C2 represents a numeric variable (checked with is.numeric(C2)). Some rows in the frame have an undefined value for C2, represented in the table by a ? sign. The remaining rows have

Hello, I have a problem with the values for one column in a table. The variable represented in this column is numeric (I get TRUE when I ask is.numeric(x)). However, the values are listed ordinally and with row numbers as values, not with the ones that appear in the table. Some rows have an undefined value for this column, which appears as ? in the table (this is not an error). I wonder whether

Hello, I have two questions: 1. How can I get black and white graphics using the pdf() device? I have tried pdf(Name.pdf, bg="white", fg"black"), but I still get full-color graphics. 2. When using lattice, how do I change the title for each panel? By default it uses the categories of the grouping factor. I would like to modify the labels in the graphic without changing

I get the error: > lnam1_01.adj<- lnam(data01$adopt,x01,ec2001.csr) Error in optim(rho, n2ll.rho, method = method, control = control, beta = parm$beta, : initial value in 'vmmin' is not

My friend Veslot proposed me the Raven ! http://www.teteamodeler.com/allopass/images/corbeau.jpg As a matter of fact the intelligence of this bird is comparable to one of a monkey, although its brain is close to a reptile brain. R is quite the same : small, compact, but so clever. This is a canadian website explaining (in french) the R-aven intelligence

My program consists of a number of functions and a main script. It loops through many time series analyzing one at a time. I have declared a number of arrays and scalar variables in the main script namespace (using C++ terminology) because those data structures ar shared by many functions. let say "XX" is he name of a global array. I wonder what happens in the following cases: 1. a

Hi all. I can't read the openssh man pages on Solaris. I tried all the nroff macro packages I could find, with more or less garbled success. Could someone point me to versions suitable for Solaris, or a man2sgml converter? Or to a good online tutorial covering this issue (SysV vs. BSD?) that would allow me to translate the nroff dialects involved? In the latter case, I would of course
