Hi. Say I have a function f with two inputs, x and y f <- function(x,y) {something} that I wish to evaluate with two input vectors of length N X <- c(x1, x2, ..., xN) Y <- c(y1, y2, ..., yN...

Hello. Is there an easy-to-use contour plot function analogous to scatterplot3d that can draw handle a dataset of arbitrary (x,y,z) triplets? That is, say x, y, and z are each measured quanties, and exhibit neither order...

Hello. Is it possible to set specify the font used by legend()? I would like to specify a fixed-width font so that I can line up parts of vertically stacked curve labels. For example, it would be nice if...

Hi. I'm having a little difficulty with R1.5.1. To wit: (1) Can anyone explain the following behavior? > a=strptime("2002-06-01 12:15:01","%Y-%m-%d %H:%M:%S") > a [1] "2002-06-01 12...

Hi. The following statement works fine in R-win 1.8.0, but yields a syntax error in R-win 2.0.1 (and possibly in other versions after 1.8.0): plot(c(1,2),main=expression(a==b...

Hi. How do I convert a one-dimensional array of characters to a character vector? In the example below I am trying to get the result c("a","d"). The function as.vector() returns the same one-dimensional array, and...

(I'm reposting this message because the original has not appeared after about 2 days. Sorry if it shows up twice.) Hello. First, thanks to those who responded to my recent inquiry about using contour() over arbitrary (x,y) by...

Hi. Can anyone suggest a simple way to obtain in R a list of vector coordinates of the following form? The code below is Mathematica. In[5]:= Flatten[Table[{i,j,k},{i,3},{j,4},{k,5}], 2] Out...

Hi. I have further experimented with the pipe() issue and found a workaround: putting the instructions in a batch file. It prepends two lines to the output of the pipe() instruction, but otherwise seems to work. -- Ronnen -- P.S. I...

Hello. I have an XYY series that I would like to graph with matplot() or some other single function that will do the trick. The X in question is a vector of POSIXt values obtained from strptime(). Is it possible...

Hello. I have an R program that calls gawk (GNU Awk 3.06 for Windows) from within pipe() to preprocess a large file before it is read into a data frame with read.table(). I've recently upgraded from Win98SE...

Hi. As shown in the simplified example below, I'm having trouble allocating memory for large vectors, even though it would appear that there is more than enough memory available. That is, even with a memory limit of 1500 MB...
