Hi,
I'm new to R (and statistics) and my boss has thrown me in the deep-end with
the following task:
We want to evaluate the impact that sampling size has on our ability to create
a robust model, or evaluate how robust the model is to sample size for the

The nice thing about R is that you can always extend it in any manner
that you want. Here is some code (that you could put in a function

writes it out, and then the dataframe itself without a column header:
out <- file('/tempxx.csv
Would this be good enough:

I've always been frustrated that R never puts a label on the column name for
a column of row names. This is usually the "key" in a database table, and
it sure would be nice to carry a "key" name along with the data instead of
the field being blank. So, why is it a good idea for it to be blank?

There is a z.test function in the TeachingDemos package, but it is
mainly for learning purposes to ease students into using t.test.
The rule of "use the normal for n>30" comes from the days when
computations were done by hand using tables and people did not want to
carry around t-tables with 100's

You can't, because A is not unique. You can easily find ***a***
solution.
Dan, I didn't realize that the t values were more accurate than the
normal approximation for n > about 30. I may have learned (incorrectly)
that the normal distribution should be used if n > 30, but now that I'm
thinking about it, this may have just been computationally economical
before computers.
B is symmetric by definition; if it's also real positive-definite then A

Since you do not change anything in your call to the function, you could
just use the replicate function instead of the for loop (I don't know
that it will speed things up much, but it is a bit more readable).

you need the RdbiPgSQL package from Bioconductor. Along with DBI, as I
recall.

Hi all,
Does anyone have the knowledge to help me identify a package capable of
forecasting a MULTIPLE regression model? i have a model with one one
dependant variable and 4 independant variables. i would like to forecast
confidence intervals for a few steps ahead...(DENSITY forecasting).

How often are you doing it? How large are your strings? What exactly
are you doing with them? Have you considered keeping them in a list
and then using 'do.call' to do the concatenation all at once? Have
you used Rprof on your program to see where time is being spent? How
much memory, and OS,
Hi!
I was trying to install the RWinEdt library on a Windows Vista machine which
had R 2.6.0, WinEdt 5.4 and the RWinEdt1.7.8.zip file in the library folder
under the ...\R\2.6.0 directory. I am able to install fine form the local zip
but I can't launch winedt from within R for some reason.
Dear Arne and Ott-Siim,
my personal opinion is that one single package is easiest both for the
useR who wants to keep track of the add-ins he might need and for the
maintainer(s) of the relevant Task Views. I'd prefer to have one single

that conceptually a bar plot starting at 500 does not
make a lot of sense and the package writers did not
entertain such an idea?
I'd suggest having a look at ?dotchart as an

You should read the vignettes for the package at:

these have the de
Maybe you can make a simple r-script (for example a jpg-plot of random
numbers, ) and run this.
This should indicate wether its due to the script or to the call to R.
From this you can work your way further down to the problem:
-if it's the script, alter your script step by step until you foun

Thanks, I should have noted that my computer system clock is fine, and as

Hi list,
I'm using barplot2 form the gplots package to plot a few numbers (I want to add
SD bars later).
However, I would like the y-axis not to start from 0 but 500. When I add the
parameters YLIM, something goes wrong. The graph is not 'cut off' at 500.
Instead the bars seems to sink trough
Dear useRs,
I am trying to draw direction fields for some differential equations. So

how to draw a direction field using R?

Hello,
using the Design library, and the following command (from the Harrell's book,

dd <- datadist(rx, age, wt, pf, pf.coded, heart, map, hg, sz, sg, ap, bm)
options(datadist=='dd')
I get the following error:
Error in datadist == "dd" : comparison (1) possible only for atomi

Perhaps:
Hi,
Try this:
do.call("rbind", lapply(a, function(x)do.call("cbind", x)))

Or just:
sapply(a, function(x)do.call("cbind", x))
If is what you want.
