Hello R-users,
I have a problem with Anova in R and I don't know how to solve that. I want
to compute Anova for each experiment (exp). I try this code:
test-lapply(split(eg,eg$Exp),function(x) aov(masa.uscat.tr ~ Clona,data =
x))
or
test-by(eg,eg$Exp, function(x) aov(masa.uscat.tr~Clona,data=x))
Dear Catalin,
Have a look at the plyr package.
library(plyr)
dlply(
eg,
.(Exp),
function(x) {
aov(masa.uscat.tr~Clona,data=x)
}
)

Dear list,
Consider these two parallel segments in a plot.
plot(c(1, 6), c(2, 2), type=n, xlim=c(0, 7), ylim=c(-2, 6))
segments(1, 1, 6, 1)
segments(1, 3, 6, 3)
How can I rotate the two lines together by a defined angle?
Thank you all in advance.
Best,

Hi
probably not most elegant and also not general but
rep(df$var[df$time==4],rle(df$group)$lengths)
or
rep(df$var[df$time==4], sapply(split(df$var,df$group), length))
shall give you desired vector.

Hello,

The only thing you have to do is to have the same variable name with the
new values.
So if predict(coxph.penal.fit, newdata[subset,]) does not work inside a
function, the following works:

I think it'd be easier and safer to save the matrix, either as an .Rdata
binary or as a text file, zip that file, and use the sendmailR tools to
attach the file to your message.

You have not provided the minimal reproducible code that the footer of this
email asks for, so we are playing 20 questions.
Perhaps you should convert the matrix to a data frame? Or is this an example of
FAQ 7.16?

OK, I'm pre-coffee, but what's wrong with using upper.tri to create a new
matrix and then multiplying that matrix by the original dat matrix (direct
multiplication, not matrix multiply) to get the desired answer?

I thought that I had provided an example of what I wanted to do but in any

FAQ 7.16 but it doesn't work in this context)
See my answer at Stack Overflow -- repeated here for anyone else who wants a

You provided examples of what you wanted, but not examples where the same code
in a different context failed to provide the result you wanted. Reproducible

I understand what you are saying. I just didn't think that showing a sendmailR
with a matrix as the body of the message would have been very helpful since it
is the fact that the received email has no content that is the problem and that
would not have shown up in the R console output.

I know you have a solution, but I would have suggested using print() with
quote=FALSE as a better way to illuminate what is going on, as in this
example:
foo - 'bahbah'
foo
[1] bah\bah
print(foo)
[1] bah\bah
print(foo, quote=FALSE)
[1] bahbah
As others said, the backslash isn't really there.
Anyone is working with the upgrade of any multilevel package for apply
sampling weights?

How can I set the horizontal axis limits on all three images to be the same

Add ylim=c(dataMin, dataMax) to each call to boxplot(), where
you specify values for dataMin and dataMax so their range is
likely to cover all your data. ('ylim', not 'xlim' - the
