Hey Bing,
Reshape's the ticker -- ?reshape.
For example, reshape(myFrame, idvar = ID, timevar = TEST.A) should
do most of the trick.

Hi Jan-Paul,
You definitely want to be careful with na.omit in randomForest -- that
wipes out any row with even one NA. If NAs are sprawled throughout your
dataset, na.omit might end up killing a lot of rows. Here's my usual MO
for missing values:
1) impute in Hmisc fills in gaps with the mean,
Can you show us the first line of the file?
The error means that in one of the values you specified as numeric (first,
second, third, fourth, fifth, seventh, eighth, ninth), it found the character
value it displayed.
Otherwise, this looks like a good use of scan.

These two lines worked for me:
rst - tapply(mydata$income, mydata$education, median)
mydata$md - rst[mydata$education]
Here's my cheesy example:
mydata - data.frame(income= round(rnorm(3, 55000, 1)),
+ education = letters[rbinom(3, 4, 1/2)+1])
rst -
Actually, what you want is sapply.

Hi
The problem is that most base plotting functions first wipe the graphics
device clean. To do what you want, you need to use par(new = T) liberally
between plots. Does that work for you?

Hi Paul,
I think lattice's histogram will do what you want, and in a friendlier
manner. Take a look at this example:
require(lattice)
a - data.frame(draw = as.vector(mapply(rnorm, rep(100, 4), rep(0, 4),
1:4)),
sd = factor(paste(sd =, rep(1:4, each = 100

I'm afraid you need to modify your approach. You're trying to pass latex an
lm object, which latex doesn't know how to handle. Also, latex isn't
supposed to produce a full .tex file; it generates just a core that's
loaded into a shell when you run dvi.
Here's an example of how you might use it
The easiest way to do that is
subset(dataframe, rate == slow).
Please let me know if you have any more questions.

Hello R world! I'm building a bundle of four packages, but I don't always
want to build the whole bundle. Usually I just want to tweak one function in
one of the packages and rebuild just that package. As such, I have
DESCRIPTION and DESCRIPTION.in files sitting in all the package folders.
Yes. See the mvtnorm package on CRAN. It implements Genz's algorithm, the
fastest method in town. (I have a version I converted to S-PLUS as well, if
you, or anyone, might need it.)

Hello everyone! I'm having the dreaded repeated rows problem in RODBC.
Specifically, when I have a NULL value in a column, odbcFetchRows reads the
value not as NULL or NA but as the most recent non-NULL value in the column.
If there is no such non-NULL column, odbcFetchRows reads the value as 0.
Hi everyone! I know segmentation faults are awfully hard to diagnose, but
I'm experiencing a fairly regular pattern of seg. faults when plotting using
map in the maps package. Starting R fresh, I run:
require(maps)
for (i in 1:50) {
cat(i, \n)
map(state)
}
I always get the same result:
