Hello, I am trying to produce an example of weighted sampling vs uniform
sampling, the subject is estimation of the size distribution by sampling
from a micrograph with a graticule of points. The sampling obtained is
thus area weighted.
I created a distribution by
pop <- rexp(1000)+rexp(1000)+re
Hello, I try to compute means,sd,n from a variable y according to some
categoricals g1,g2... I wrote the following function:
msd<-function(y,...) {
print(match.call())
funy<-function(x) list(mean(x,na.rm=T),sd(x,na.rm=T),table(is.na(x))[1])
gg <- list(...)
aa<-by(y,gg,funy)
bb<-matr
in this case is coef(), as in
coef(lo)[4]

Hello, I have a program with this section:

If the fit works this is OK but if the fit fails, the whole program
fails so:
..
for(i in 1:20){
try(lo <-
nls(y~y0+a/(1+(x/x0
I just downloaded Affy in R 1.8, Also downloaded
Biobase,reposTools,tkWidgets,genefilter.
when called

HI,
no sorry, so far nobody answer. So it probably does not have a solution.
