Population pyramids
Hi, I hope somebody can help me with this issue: I am doing population pyramids using the barplot command, so in the left side I have male age structure and in the right side the female age structure. To plot the male age structure I put the data in negative numbers. Now, I want to change the sign in the bar plot in such way that I have no-sign numbers, both in left and right side of the graph. I

Using ifelse and grep
Good Morning,
I am trying to create a new column of character strings based on the first
two letters in a string in another column. I believe that I need to use some
combination of ifelse and grep but I am not totally sure how to combine
them. I am not totally sure why the command below isn't working. Obviously
it isn't finding anything that matches my criteria but I am not sure why.

How the change the dimension of an individual cell [i.e. the cell corresponding to an observation in data matrix] in a heatmap.2?
Dear R-Helpers,
I have a short question related to heatmap.2 function. I wanted to change
the dimension of each cell in the heatmap drawn by this function.
here is a reproducible example from the help page
library(gplots)
data(mtcars)
x <- as.matrix(mtcars)
rc <- rainbow(nrow(x), start=0, end=.3)
cc <- rainbow(ncol(x), start=0, end=.3)

estimate inverse gaussian in R
I have a one-variable data set in R.
The plot of histogram of my numerical variable suggests an inverse
gaussian distribution.
How can I obtain best estimation for the two parameters of inverse
gaussian based on my data?
Thanks.

GAMM : how to use a smoother for some levels of a variable, and a linear effect for other levels?
Hi,
I was reading the book on "Mixed Effects Models and Extensions in
Ecology with R" by Zuur et al.
In Section 6.2, an example is discussed where a gamm-model is fitted,
with a smoother for time, which differs for each value of ID (4
different bird species). In earlier versions of R, the following code
was used

concordance correlation coefficient using R
Hi.
I have data which i would want to assess the degree of agreement
between two assays, e.g., to evaluate reproducibility or for
inter-rater reliability. I have used the Pearson product-moment
correlation coefficient. It looks good ranginging between 0.90 to
0.998. Though this looks good. I am told the Concordance correlation
coefficient will give a better picture of how reproducible the assay

Version 0.7 of package tsDyn, nonlinear time series
Hi
Version 0.7 of package tsDyn presented at useR! 2009 is now on CRAN,
extended with several new features.
The package tsDyn is aimed at estimating nonlinear time series models
which exhibit regime specific properties. The regime switching dynamics
can either be described by smooth transition (STAR and LSTAR) or
threshold effects (SETAR). The package furthermore offers nonlinear
