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!

...pp1 <- as(mat1, "gpc.poly") ? m <-max( (max(coredata(ts01)) - bl)/3, abs(min(coredata(ts01)) - bl)/3) m1 <- bl+m m2 <- bl+2*m ? ##### cutting the blue poly above the baseline # poly above the baseline s1 <- setdiff(pp1, pp2) y2 <- rep(m1, length(index(ts01))) mat2a <- cbind(c(index(ts01)[1],index(ts01), index(ts01)[length(index(ts01))]), c(bl[[1]], y2, bl[[1]])) pp2a <- as(mat2a, "gpc.poly") ? # poly above baseline between baseline and first horizontal line at m1 sa1 <- intersect(pp2a,s1) ? # remaining polygon - translate polygon down...

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",
