Hi, I have created an R package in which I implement my own version of the "as.dataframe" function. However when I load up my package into R, it seems to mask the original version of "as.data.frame". Is there to limit/control the scope of the "as.data.frame" function defined in the my package so that it does not interfere with the original function? Maybe by using

Hello, I am trying to use the package "exams" to construct problem sets. I have constructed an exercise which generates a list of integers and asks the student to compute the median. rx is the vector of n numbers >str(rx) num [1:16] 21 9 8 18 4 12 17 2 9 7 ... I want to print out the entire vector as part of the problem. When I use \Sexpr(rx) only the first value (in this case

I'm rather puzzled by this behavior: e export("caption<-", "caption", "label", "label<-", "align<-", "align", "digits<-", "digits", "display<-", "display", "xtable", "print.xtable", "toLatex.xtable") > e[[1L]] e[[1L]] export >

I've been experimenting recently with the fantastic Sweave/xtable combination for generating latex. In the xtable vignette, I found this great example of printing a ts object by months. Is there a way to modify this code to generate RED numbers inside xtable for negative results in x.ts? Thanks in advance. - Ken # Sweave/xtable snippet below

I am just starting to learn Sweave (really neat tool). I am pretty early in the learning curve (I had to think a moment ago whether a # or % was the appropriate comment character). I have successfully incorporated simple graphics and outputs, but am having trouble getting a latex (xtable) table to function properly. Latex is seemingly treating the xtable code as input or verbatim text. That

Hi there, I'm very new on R and I hope someone can help me to solve the problem in using the ifelse statement with the xtable function(library xtable). I'm trying to get the printing of the elements of two lists in a sorted way. These two list have in common the their names. I will try to give an example: the first list looks like this: $code1 Code code1 Nation

Hi all, Let me know if I need to ask this question of the bioconductor group. I used the bioconductor utility to install this package and also the CRAN package.install function. My computer crashed a week ago. Today I reinstalled all my bioconductor/R packages. One of my scripts is giving me the following error: in my script I set: library("xtable") print.xtable(.... and receive this

Dear R help: I am trying to use paste(), within an ifelse() statement to insert latex commands into an object that has been created using xtable(). I cannot make the strings behave as I would like, the '\t' is creating a tab, the usual method of '\\t' is not working either - nor is any series of backslashes. The xtable object, I think, automatically alters the strings. How

Hola Tengo un problema con Sweave y xtable, concretamente quiero cambiar el color según un criterio, creo que es más fácil explicar con los siguientes ejemplos, uno puede correr directamente porque es R, al siguiente código hay que guardarlo como Rnw, y luego puede ser corrido en R, donde seguramente al correr este se darán cuenta de mis dos problemas porque saltan al abrir el pdf que se obtiene

Dear R-users, I've enhanced the "xtable" package, adding numerous features that have been requested by users. The changes are listed below. The objective throughout has been to avoid any breaking changes. However, as "xtable" is widely used and is a dependency of many packages I'd like to have others try it out before I post it to CRAN. Both bug reports and design

I'm trying to get Sweave running for automatic report generation, and it seems to run fine when just using verbatim output. However, I've ran into a problem with xtable. I would like to print the following matrix using xtable: > dim(counts) [1] 19 15 All columns are filled with real/integer numbers > 0 and < 1000. Just typing xtable(counts) gives correct LaTeX output, but
