Hi,

Hi Val,
Does this help:
library(plyr)
ddply(as.data.frame(xc3), .variables = "xc1", summarise, d1 = sum(xc2 ==
0), d2 = sum(xc2 == 1))
You could also try
aggregate(xc3, by = list(xc1, xc2), FUN = sum)
and modify the output.

Hi.
You should check function addtable2plot from plotrix package.
Also, here is an example of modified addtable2plot function that I

Hi all
Just a quick question which I can't find an answer for in the usual places:
I would like to create a table of regression output, with one or more
regressions in the columns, a la xtable. But I am using models from the
Design package. Is there anything out there that will play nicely with th

You can always save the (numeric version of the) names as an object, too
It isn't entirely clear to me what you want.
table() can function with many kinds of data, not just integers, so it
returns a vector with names.
For your case, with integer classes, you seem to possibly want:

This is!
Thank you everyone.

try the following:
DF <- as.data.frame(matrix(sample(2, 120, TRUE), 10, 12))
Results <- data.frame(
var = names(DF),
count = colSums(DF == 1),
percentage = colMeans(DF == 1)
)
I hope it helps.
Best,

Running ‘table’ on a factor with levels containing non-ASCII characters
seems to result in *extremely* bad performance on Windows. Here’s a simple
example with benchmark results (I’ve reduced the number of replications to
make the function finish within reasonable time):
library(rbenchmark)

This is a "tableplot", available on R-Forge at
https://r-forge.r-project.org/projects/tableplot/
install.packages("tableplot", repos="http://R-Forge.R-project.org";)
will install, as long as you are using R 2.12.x; otherwise, you'll
have to download the source package and install from source.

I was just thinking of a way to present data and if it is possible in R.
I have a data frame that looks as follows (this is just mockup data).
df
location,"species1","species2","species3","species4","species5"
"loc1",0.44,0.28,0.37,-0.24,0.41
"loc2",0.54,0.62,0.34,0.52,0.71
"loc3",-0.33,0.75,-0.
for the loop part:
put all your xml files in a directory with no other files,
do
setwd("directory/with/xml/files")
files <- list.files()
for (file in files)

Hi Jørgen,
You will be better served by learning how to find the answers to these
kinds of questions on your own. You can either use a general search
engine such as google:

http://lmgtfy.com/?q=read+xml+data+in+R
or using an R specific search engine. At
