...2002 month 11 day 01 language R > gawk is in my system path, and I can successfully run it from a command window. Hence, I have the following questions: (1) Is pipe() supported in R1.6.1 under WinXP? (2) Can anyone suggest how to get pipe("gawk...") to work again? Thanks, Ronnen. P.S.

...t;) points(x,y) I would have expected the lower and upper prediction intervals to converge as x increases (and the noise decreases), but they seem to remain virtually equidistant. Can anyone explain (a) the behavior that I see, and (b) how to obtain curves that do bound the noise?

..., even with a memory limit of 1500 MB, R 2.6.1 (Win) will allocate memory for a first vector of 285 MB, but not for a second vector of the same size. Forcing garbage collection does not seem to solve the problem. Can anyone explain why is this happening, and how to fix it? Thanks, Ronnen. P.S.

...rtically stacked curve labels. For example, it would be nice if I could align the names, ages, and weights in the following three curve labels: Bob age=7 weight=100 Alexander age=13 weight=150 Susan age=20 weight=130 Is there perhaps a clever solution involving expression()?

Hi. I often wind up with many help windows cluttering my RGui screen when running Windows R 2.0.1. Is there an R instruction to close one or more help windows, or an RGui command to close all help windows? Yours truly, /Ronnen. /P.S. E-mailed CC:s of posted replies appreciated.
