Hi there,
I have a data set file, called "ecotox.rep", which is a delimited file
separated with "|".
When I tried to read the file with the following command,
> df <- read.table("ecotox.rep", sep = "|", header = TRUE,
stringsAsFactors=FALSE)
I got the error messages:
Error in scan(file =

Hi there,
I notice that write.csv is a wrap of write.table. However, I can't get
the same results using both functions. Here is a reproducible example:
> x <- matrix(1:6, nrow =2)
> rownames(x) <- letters[1:2]
> colnames(x) <- LETTERS[1:3]
> write.csv(x, "")

Hi there,
The following is a simple design. A and B are factors with their levels
randomly selected. In other words, A and B are random.
The data is recorded in "abc", as:
> dput(abc)
structure(list(water = c(12.1, 12.1, 12.8, 12.8, 14.4, 14.4,
14.7, 14.5, 23.1, 23.4, 28.1, 28.8), A = structur
Hi there,
Does anyone here know where does the R Graph Gallery
(http://addictedtor.free.fr/graphiques/) move to? I googled, but don't
find any useful hints.
Any help? Thanks in advance!

Hi there,
It's a off-topic post. It seems that the R home page changed a lot.
There are no plot at the right frame. Why are they removed? Will it or
an alternative be back in future?
Another question is about the ``What's New?'' page. The latest
announcement is not archived in that page. In
