This question is about including code and R results in Latex trough Sweave. It works fine and is of great help. Now may question is how to get the code and the output computed by R within a frame in Latex. Does any one have an idea on that. I tried \fbox, etc. but it seems to have problems with the code chunk generation of Sweave and I ger errors. I would appreciate any suggestion. I'll

Library gmodels include a function CrossTable that is useful for crosstabulation. In the help, it is indicated that one can call this function as CrossTable(data), were data is a matrix. However, when I try to use this option, it doesn't help. Any idea? Is there a bug? Thanks for your help.

This is a generic request concerning were to look for finding appropriate information on a precise procedure in R. I’m using R for teaching introductory statistics and my students are learning how to deal with it. However, I find it difficult to locate some of the procedures. For instance, for basic crosstabulation, it is obvious that basic functions as table, ftable, and prop.table can be used.

I’m trying to obtain a plot of given function, say the density of a normal, in which I could indicate the area under the curve between two points (a,b). I.e. the P(a<X<b). Could anyone indicate me which is the instruction for obtain such a shadow area under a curve? I guess the solution is not difficult, but I can not find the procedure.

Hello, I have two vectors, one with 13112 points and the other one with 10909.

Hello, I have the next function call: lme(fixed=Error ~ Temperature * Tumour ,random = ~1|ID, data=error_DB) which returns an lme object. I am interested on carrying out some kind of lsmeans on the data returned, but I cannot find any function to do this in R. I'have seen the effect() function, but it does not work with lme objects. Any idea? Best, Dani -- Daniel Valverde Saub? Grup
