Hi All, I have a rather naive question. I need to run some simple calculations such as read.table, resid, and quantile on a data file. How can I save these commands in a text file and ask R to run this text file? Thanks.

Hi All, I had 12766 elements in a column, 12566 are values and 200 are "NA"s. I used the following line to get the ranks: total_list$MB.rank <- rank(-total_list$MB,ties.method="min",na.last=NA) but I got an error message: Error in `$<-.data.frame`(`*tmp*`, "BCRP_PW_F.rank", value = c(3949, 6182, : replacement has 12199 rows, data has 12766 What

Hi All, I typed "pairs" to see its code but did not get what I want. How do I see its code? What I am trying to do, is to stack about 10 scatter plots on one page as the way "pairs" does. I have about 150 variables in my table. Instead of plotting 150X150 pairs using "pairs", I only need to plot 10 pairs. Thanks. jiong The email message (and any attachments) is

Dear all, I would like to generate 25 numbers from 1 to 100 but I would like to have some numbers that could be more probable to come out. I was thinking of the function runif: runif(25, 1, 100) , but I don?t know how to give more weight to some numbers. Example: each number from 2 to 10 has the probability of 40% to come out but the probability of each number from 11 to 100 to come out is

I'm using scan in a script to record a series of responses of the user as a function of some graphs that I put up on the screen. A toy version would be, y <- rep(NA, 3) for (ix in seq( length(y) ) ) { y[ix] <- scan( n = 1 ) } However, if I include any code after this loop, for example, y <- rep(NA, 3) for (ix in seq( length(y) ) ) { y[ix] <- scan( n = 1 ) } y I get an error

I rebuilt a test version of my yaImpute package using Uwe Ligges' windows build service.

Dear r-helpers, I wonder whether, given the "#rrggbb" representation of a colour, there is a simple way to select the complementary colour, also expressed as a "#rrggbb" string.

Hello, The function barplot automatically creates a y-axis that doesn't necessarily cover the range of y-values to be plotted. I know how to manually create my own y-axis so that it does cover the range, but I was wondering if there is some parameter to change so that the scale of the y-axis is automatically taller than the tallest bar. I thought setting xpd=F would do it, since it says that

Hi, Is there a function for raising a matrix to a power? For example if you like to compute A%*%A%*%A, is there an abbreviation similar to A^3?

Dear list: I have some data for which I am generating a series of barplots for percentages. One issue that I am dealing with is that I am trying to get the legend to print in a fixed location for each chart generated by the data. Because these charts are being created in a loop, with different data, my code searches the data to identify the maximum value in the data and then print the data values

It sounds like the general functionality level is high enough. Taking it into mainline sounds

Hi all, I'd like to do cross-validation on lm and get the resulting lift curve/table (or, alternatively, the estimates on 100% of my data with which I can get lift). If such a thing doesn't exist, could it be derived using cv.lm, or would we need to start from scratch? Thanks! -- Eric Siegel, Ph.D. President Prediction Impact, Inc.
