array
Hello,
I have some files generated from microarray experiments. I used scan() to
read the files, and assigned each file to a unique name with many rows and
columns. Now I want to create a array (ArrayA) with unique names, and I can
use ArrayA[1,2][[6]] to refer the data in each file. Is there any packages
available for array of array?
Thanks!

Simple question on replace a matrix row
Hello, I have a matrix mat1 of dim [1,8] and mat2 of dim[30,8], I want to
replace the first row of mat2 with mat1, this is what I do:
mat2[1,]<-mat1 but it transforms mat2 in a list I don't understand, I want
it to stay a matrix...

merging dataframes
Dear List,
I often have to merge two or more data frames containing unique row
names but with some columns (names) common to the two data frames and
some columns not common. This toy example will explain the kind of setup
I am talking about:
mat1 <- as.data.frame(matrix(rnorm(20), nrow = 5))
mat2 <- as.data.frame(matrix(rnorm(20), nrow = 4))
rownames(mat1) <- paste("site",
