Hmisc summary.formula formats for binary and continuous variables
Hello,
I am using Hmisc summary.formula, latex and Sweave to produce tables for publication. Is it possible to change the formats for binary and continuous variables? I would prefer to show 35 (10%) and 1.5 (1.2-1.8) rather than 10% (35) and 1.2 / 1.5 / 1.8. Here is a simple example:
sex <- factor(sample(c("m","f"), 500, rep=TRUE))
age <- rnorm(500, 50, 5)

paste dont get the teste elements separately to join again in a unique

CI with confint
Hello all,
I'm trying to use confint from the MASS package to compute confidence
intervals for an nls object. When I plot the results, however, they don't
make sense - lines cross over the fitted model or just don't match the
data. Code is :
Thanks for help
dat<-data.frame(a,b)
with(dat, plot(a,b))

Difficulties with for() {while(){}}
Hi,
I have the follow function:
function() {
## Init of function
...
for(i in test) {
...
while(j <= test2) {
...
}
}
}
The problem is that sometimes, naturally, the while is not possible to be
resolved, and so the program abort.
In this case I need that program return to the init of function and run again.
How I can make this? Abort the while, abort the for
