par code help
I am making a barplot using barplot2 from gplots where each bar
represents a specific tree species. I have formatted the species names
on the x-axis so that the genus name is above the species name and
have then rotated the labels 45 degrees to save room. This is my code:
>columncolor<-c("grey20", "grey20", "grey20", "grey70",

Formatting names.arg
I am making a barplot using barplot2 from gplots and would like to
format the names of my categorical variables (tree species) on the x-
axis so that the genus name is above the species name (to save room).
My code so far is:
speciesnames<-c("Dialium guianensis", "Inga alba", "Tachigali

prop.trend.test issue
I have the clinical study data.
Year 0 Year 3
Retinol (nmol/L) N Mean +-sd Mean +-sd
Vitamin A group 73 1.89+-0.36 2.06+-0.53
Trace group 57 1.83+-0.31 1.78+-0.30
where N is the number of male for the clinical study.
I want to test if the mean serum retinol has increased over 3 years
among subjects in the vitamin A group.

some help regarding combining columns from different files
Dear all,
Here is my code which am using to combine 5th column from different data
sets.
Here is the function to do my job
genesymbol.append.file <-NULL
gene.column <- NULL
readGeneSymbol <- function(files,genesymbol.column=5){
for(i in fnames){
temp <- read.table(fnames,header=T,sep="\t",stringsAsFactors=F,quote="\"")

help combining mtext and strwrap?
Hi all,
I've got some image plots on which I'd like to include some gene information
(in the margins using mtext). Unfortunately, the description is rather long
and will need to be wrapped to fit on several lines. From what I know about
mtext, it's really only meant for single-line labels, not paragraphs.
Here's some sample code of the idea I'm trying to accomplish:

italics help in plot
Part of my script reads:
speciesName <- names(data)[i]
plot(year,depth, xlab="Year",
ylab="Depth(m)",main=expression(italic(paste(speciesName))) )
Unfortunately, this just plots *speciesName *on my graph, not the name of
the species in italics. Any suggestions on how to resolve this?
Thank you

How do I wrap a long mixed text/math expression in an axis label?
I would like to wrap a y-axis label onto two lines. My label is an expression
containing both text and math symbols. I have looked at plotmath,
strsplit(), strwrap(), deparse(), do.call(), substitute() and bquote().
Based on previous posts, I can get plain text to wrap. However, when I try
these methods on my label, the exact string is returned, rather than
evaluating the math symbols.

neatmap - draw.dendrogram - help!
Hi all,
I'm having a problem where by I'm trying to use the NeatMap draw.dendrogram
function as it is more versatile in placement/direction of dendrograms,
instead of the limited plot function.
Using plot I can get my dendrograms to display the species name for each
leaf of the tree. But I cannot figure out how to make this happen using
draw.dendrogram..

' quote problem in reading lots of files at once
Dear group,
i have 114 files (all have 5 columns) and variable
number of rows.
I want to read all the files and select the first
column and 4th column and fill the values into a big
matrix. I have a pre-made matrix that would have all
rownames (1st column) and coloumn names (4th column
from file to be read).

adding zeros to dataframe
Greetings,
I am new to R and am hoping to get some tips from experienced R-programmers.
I have a dataset that I've read into R as a dataframe. There are 5 columns: Plot location,species name, a species number code (unique to each species name), abundance, and treatment. There are 272 plots in each treatment, but only the plots in which the species was recorded have an abundance value. For
