invalid 'row.names' length error when running scatterplots or plot in R Commander
Hello,
I teach statistics and use R Commander for teaching. I have 2 students
out of 169 that can't get scatterplots or plot to work. I have had them
update packages, restart R/R Commander/their computers and even
reinstall R/R Commander. One is using Windows 7 on a new pc and the
other is a pc user (not sure the OS). They are both using R2.11.1 and R

lmomco in gev estimation
Hi guys,
I'm trying to use lmomco package. first I did the manual calculation on
what is the estimates scale and location parameter given L-CV=0.2, L1=1000
L-moments and k (shape parameter) =- 0.1. so what i get is:
location: 821.0445
scale: 260.7590
shape: -0.1000
#I assign this as GEV vectors using vec2par
GEVpara2<-vec2par(c( 821.0445 , 260.7590 ,-0.1),'gev')

Saving fExtremes estimates and k-block return level with confidence intervals.
I am estimating a large model by groups. How do you save the results and?returns
the associated quantiles?

Matrix scalar operation that saves memory?
One possibility might be to use Rcpp.
An R matrix is stored in contiguous memory, which can be considered as a
vector.
Define a C++ function which operates on a vector in place, as in the
following:
library(Rcpp)
cppFunction(
'void subtractConst(NumericVector x, double c) {
for ( int i = 0; i < x.size(); ++i)
x[i] = x[i] - c;
}')
Try this function out on a matrix. Here we

block statistics with POSIX classes
I have a monthly price index series x, the related return series y = diff(log(x)) and a POSIXlt date-time variable dp. I would like to apply annual blocks to compute for example annual block maxima and mean of y.
When studying the POSIX classes, in the first stage of the learning curve, I computed the maximum drawdown of x:

Question on Simple Repeated Loops
Dear R-User,
Appreciate any helps. It looks simple, but I don't have a clue.
Given that I have a dataframe of tree population with three variables:

How can I calculate the future growth increment of each tree for the next 3 years.

differences between survival models between STATA and R
Dear Community,
I have been using two types of survival programs to analyse a data set.
The first one is an R function called aftreg. The second one an STATA
function called streg.
Both of them include the same analyisis with a weibull distribution. Yet,
results are very different.
Shouldn't the results be the same?
Kind regards,

Matrix scalar operation that saves memory?
I doubt that R's basic matrix capabilities can handle this, but have a look
at the Matrix package, especially if your matrix is some special form.

wire.frame tick labels from matrix
Dear R Users, close to the end of this I used wireframe to create a 3D plot
from a matrix. The x and y axis tick labels (1-6) for each were created
from the matrix being a 6X6 matrix. I need the axis tick labels to be the
row and column headings which you can see in the output (mat.x). I have
tried several work arounds, but they have not been successful.
Thanks in advance. keith

Dear useRs,
i want to split a matrix having 1116rows and 12 columns. i want to split that matrix into 36 small matrices each having 12 columns and 31 rows. The big matrix should be splitted row wise. which means that the first small matrix should copy values which are in first 31 rows and 12 columns of the big matrix. similarly 2nd small matrix should contain values from 32nd to 63rd row of the

SAS and RODBC
I am using R-2.10.1 binary from CRAN on a WinXP Pro system. I also use SAS v9.2 on the same box. I just started using the SAS ODBC driver that comes with version 9 of SAS. I have been able to set up an ODBC source for SAS datasets using the driver, and then with RODBC I am able to read a sample SAS dataset.
