I am trying to save some graphical output including a legend in the
Windows Enhanced Metafile (EMF) format.
This fails when xyplot() is used rather than plot().
Here is a simple example:
require(lattice)
a <- c(1:10)
b <- c(2,4,5,2,3,5,7,8,9,5)
# Output can be saved (or copied to the clipboard)
This is my first attempt at this, so hopefully a few kind pointers can get me
going in the right direction...
I have a large data frame of 20+ columns and 20,000 rows. I'd like to
evaluate the distribution of values in each row, to determine whether they

Hi Sujatha,

It is not clear what you are trying to do, but you can have lists (or vectors)

Hi Chris,
'gsub' does exactly what you want:
gsub(",","",text)
so there is no need for a loop.
Btw. your loop assigns a new value to m in each step and you see only
the last assignment.
you could do something like
m <- paste(m,substring(text,i,i+2),sep = "")

You can use the summary with the split argument.
See
?summary.aov
for an example.
This gives similar results to the regression coefficients approach that Ista
Zahn
suggested. I usually prefer the ANOVA table approach for factors.

Hi,
If you do
test <- summary(aov(DV ~ IV1 * IV2))
str(test)
you will see that
test[[1]][2]
gives you what you want.
Reading more on indexing will also probably help you. str() is a very
useful function, to use without moderation!

Hello R-help
(sorry if this message gets posted twice, i think I may have accidently
postponed it)
I donât know how to interpret significance from the contr.poly() function .
From
the example below
: how can I tell if data has a significant Linear/quadratic/cubic trend?

Hello there
I have the following model based on the hollings disc equation for the type
II functional response for 2 data sets:
nls(eaten~(a*suppl)/(1+a*h*suppl)
where eaten is the number of prey eaten by a predator and suppl is the
number of prey initially supplied to the same predator.

Notice that the third call is different, you have 3 args in

Hi,
I have a function myFun which I want to call multiple times, using different
argument lists.
myFun("v1", "2009", 1)
myFun("v2", "2008", 1)
myFun("q", "2001")
How can I easily do this in R? Should I use mapply?
I unsuccessfully tried something like:
x <- list(c("v1", "2009", 1), c("v2", "200
