Hi: I am working on a publication and I have heard about LaTEX but I haven't actually tried to learn about it until today. I've found a few examples but I can't actually make them work properly. I have a couple of questions: Does LATEX have to be installed on your computer? How does the xtable package and Sweave work together? How can I make the code below create a table as pdf file?

Hi: Could someone try to run this example? I can't make it work. ## Not run: \begin{small} \setlongtables \begin{longtable}{ <<results=tex,fig=FALSE>>= cat(paste(c('c', rep('cc', 34/2-1), 'c'), collapse='@{\hspace{2pt}}')) @ } \hline \endhead \hline \endfoot <<results=tex,fig=FALSE>>= library(xtable) set.seed(2345) res

Hi: My head is spinning with this latex doc so hopefully after I align my tables to the left of the page my headache are going to be over. I always use: \hspace*{-0.1in} to move my figures horizontally to the left margin of the page but the table below doesn't move at all, but instead it gets sideways. Not sure if \begin{landscape} has something to do with it or is just me. I? hope someone

Hello R-List I've run into a minor problem with ggplot2. In particular, I get an error message when trying to plot a horizonal line through zero. Here is what I do: plt.df <- subset(xfm.df, select=c(stage, subj, tX)) plt <- ggplot(pp.df, aes(x=stage, y=tX, group=subj)) + geom_line() plt plt <- plt + geom_hline(intercept=0) plt The first plot yields a most lovely graph.

Hi I have a long data set on which I want to do Bland-Altman style plots for each rhythm type Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels. I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example: > lvexs cvd_basestudy ecd_rhythm fixed_time variable_time 1 CBP05J02

Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

Hi: I am going through some of the xtable examples and I can't make the one below work. I need to create a longtable on the fly keeping the column headers for all the pages and I thought this example could give some ideas on how to do it. I am using Sweave and xtable to create my tables and graphics. I wonder if someone could tell me what's wrong. Thanks ## Not run: \begin{small}

Hello all: Is there a way to detect in R if a dataset is normally distributed or skewed without graphically seeing it? The reason I want to be able to do this is because I have developed and application with Visual Basic where Word,Access and Excel "talk" to each other and I want to integrate R to this application to estimate confidence intervals on fish sizes (mm). I basically want to
