Dear R-Help,
I am using the 'mfp' package. It produces three plots (as I am using
the Cox model) simultaneously which can be viewed together using the
following code:
fit <-
mfp(Surv(rem.Remtime,rem.Rcens)~fp(age)+strata(rpa),family=cox,data=nearma,select=0.05,verbose=TRUE)
par(mfrow=c(2,2))
pl
i am working with two sets of likert scale type (4 distinct values) data:
dataA <- rep(1:4, c(3,2,2,4))
dataB <- rep(1:4, c(5,4,3,2))
i can now (bar)plot both of these separately and compare the distributions.
plot(table(dataA), type='h')
plot(table(dataB), type='h')
is there a way to plot both
Yes. We will release a version in the next few weeks
when I have time to wrap it all up.
There is also a Docbook-based version that uses
R extensions to Docbook for authoring structured
documents.

Usually 10-fold cross validation is performed more than once to get an
estimate of the misclassification rate thus I thought "number of
cross-validations" was different from the "number of cross-validation
groups". So, if I want to perform 10-fold cross-validation more than once

It is the same thing.

Dear R users,
I'm working with the rpart package and want to evaluate the performance of

I have some problems in understanding the meaning of the xval argument in
the two functions rpart.control and xpred.rpart. In the former it is defined
as the number of cross-v
An example:

Have a look at the merge function.
"Merge two data frames by common columns or row names, or do other
versions of database _join_ operations."

I've got two data.frames and, when certain "keys" match, I would like to add
the column values from one data frame to the other data.frame.
Below I list the two data.frames, i.e. neighborhoodInfo_df, and schoolZone_df.
Based on the "address" key I would like to add the "schoolZone" key to the
