Hi, after reading some R docs, I couldnt figure out how can I find the
solution for the following
problem, therefore I would ask this friendly list for an advice.
Were making a least square approximation for an experiment described by the
following model:
T is the time,
Y is some measured
Since you want least squares, I think you could use lm() here, i.e.,
U - 50
V - 100
Time - 1:150
dat - data.frame(y = rnorm(150), Time, f1 = as.numeric(Time U), f2
= as.numeric(Time V))
###
m - lm(y ~ Time + I(Time - U):f1 + I(Time - V):f2, data = dat)
# check also the design

I always thought that ability to see and study the code of every package,
was a great thing about R and other open source environments. So I hope
there are no good ways of hiding the code of packages.

I am struggling with migrating some stata code to R. I have a data
frame containing, sometimes, repeat observations (rows) of the same
family. I want to keep only one observation per family, selecting
that observation according to some other variable. An example data
frame is:

I don't know how to read data from posgresql to R.
Does anybody can help me?

Here is one way this can be done
do.call(rbind, by(dat, list(dat$fam) ,function(x) {

Dear R-list,
does an R-package exist in which the Clayton-Oakes failure time model is
implemented?

if you also need to create the `keep' vector, then you could try this
approach:
fam - c(1,2,3,3,4,4,4)
wt - c(1,1,0.6,0.4,0.4,0.4,0.2)
dat - data.frame(fam, wt)
###
keep - unlist( lapply(split(wt, fam), function(x){
ind - rep(FALSE, length(x))
ind[which.max(x)] - TRUE
In case you want to estimate U and V as well, there's a segmented regression
package (called segmented) on http://cran.r-project.org for this.

There's something else you could try - since you can't hide the code,
obfuscate it. Hide the real thing in a large pile of useless,
complicated, awfully formatted code that would stop anyone except the
most desperate (including yourself, after a couple of weeks/months)
from trying to understand

Sorry about late response but I was traveling and did not follow R-Help for

have a full control of IO formats. I like to store images as integer or real
