[R] does save.image() also save the random state?

Re: [R] Subset with missing argument within a function

R's subscripting operators do not "guess" the value of a missing argument: a missing k'th subscript means seq_len(dim(x)[k]). I bet that you use syntax like x[,1] (the entire first column of x) all the time and that you don't want this syntax to go away. Some languages use a placeholder like '.'

[R] Create macro_var in R

[R] Alignment of a double plot where one has a switched axis

Hi Rgonauts, I am plotting 3 variables from one data set on one plot. Two of them as a stacked bar and a ratio on a completely different scale, so I need to put one of the axes on the top of the plot for clarity. Whilst this is not good visualisation practice, there is a valid reason why,

[R] reading in multiple data sets in 2 loops

Hello, I have over 1000 csv data sets I need to read into R, so I want to read them in using a loop. The data sets are named as pheno_1000ind_4000m_add_h70_prog_1_2.csv, pheno_1000ind_4000m_add_h70_prog_1_3.csv, ... so I need 2 loops (for the last 2 numbers in the names). What I would like to do

Re: [R] Create macro_var in R

If 'tab' is a data.frame then new.tab <- tab[[mvar]] is a column from that data.frame, not a data.frame with one column. new.tab <- tab[ , mvar, drop=FALSE ] will give you a data.frame that you can add to with either of nvar <- "newName" new.tab[ , nvar] <- newColumn new.tab[[nvar]]

Re: [R] Create macro_var in R

Yes, you can use a name stored in a variable to create a new column in a data frame (guessing that's what you want). Here's an example: > df <- data.frame(a=1:5) > df[['b']] <- 2:6 > df a b 1 1 2 2 2 3 3 3 4 4 4 5 5 5 6 > mvar <- 'c' > df[[mvar]] <- 0:4 > df a b c 1 1 2 0 2 2 3 1 3 3 4 2 4 4

Re: [R] Create macro_var in R

You REALLY NEED to read the "Introduction to R" document discussion of indexing. tab is a variable. It is apparently a data.frame. tab[[mvar]] is an expression that retrieves part of the data in the tab data.frame. The data it returns is a vector, not a data.frame. The "[[" operator

You are trying to use shortcuts where shortcuts are not appropriate and having to go a lot longer around than if you did not use the shortcut, see fortune(312). You should really reread the help page: help("[[") and section 6.1 of An Introduction to R. Basically you should be able to do
