Need help with pipe()
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 to WinXP, and have also upgraded
from R1.5.0 to R1.6.1 over the past month or so. This program worked
before the upgrade(s), but now fails. I observe the following sort of
behavior with

Prediction Intervals (reposting)
(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 mentioning the interp() function in
the akima package. That worked nicely. Now for a new question:
I would like to use a pair of prediction intervals to

Generating list of vector coordinates
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.

Out[5]=

Contour plot for arbitrary (x,y,z)
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
nor regularity.
I looked at the lattice package function "contourplot" but it seems
complicated, and it's not clear from the documentation whether it can

Trouble with expression() in R-win 2.0.1
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==c))
I note that the following workaround executes successfully in both
versions of R...
plot(c(1,2),main=expression(a*"="*b*"="*c))

Legends and Fonts
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 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

Formatting POSIXt values in plot axis labels
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 to tell matplot() how to handle POSIXt x values?
I have examined the examples at

Closing RGui help windows
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,

Plotting polynomial fit
Hi.
Is there an analog to abline() that can be used to plot a polynomial fit?
For example, I can draw the straight-line fit
fit <- lm(y ~ x)
via
abline(coef=fit$coef)
but I'm not sure how to draw the polynomial fit
fit <- lm(y ~ poly(x,2))
I do see the function curve(), but not how to prepare an expr for
curve() based on the coefficients returned by the polynomial

Order a vector and move to new vector
I currently have a data frame with a Fund ID and NAV value. Is it possible
to order the data frame and move to separate columns in a new data frame or
matrix in R without using a for loop? I suppose I'd like to use a built in
function to make it faster because I will have around 60,000 entries to sort
and my current program takes too long to do this. I know how to use order,

OpenSSH slow on OSX High Sierra (maybe due to libcrypto)?
Hi all.
Is anyone else seeing issues with OpenSSH being slow on OSX High
Sierra? In the interests of better test coverage I set one up,
however the OpenSSH tests take much longer on it than on much older
machines with much slower CPUs. It seems to be due to the
vendor-supplied libcrypto being about 20x slower at bignum operations
than nominally the same version of LibreSSL compiled locally.

Creating R packages, passing by reference and oo R.
Dear All,
I would like some advice on creating R packages, passing by reference and oo R.
I have created a package that is neither elegant nor extensible and rather cumbersome (it works). I would like to re write the code to make the package distributable (should it be of interest) and easy to maintain.
The package is for Bayesian model determination via a reversible jump algorithm and has
