Hi R-users,
I have created a Conditional Tree using the ctree function ( in package
partykit). The data had a factor - the y variable - and a host of
categorical x-variables.
Now, I want to find the proportion of cases where y = 1 in each of the
terminal nodes.
Is it possible to do so programmat

(just a comment)
and since this appears to be O(m^2 x n), where m,n are the number of
rows and columns (correction requested if I got this wrong), it would
appear that some basically C level functionality -- perhaps the one
Jean suggested? -- would be required for even moderately "large"

Jorge,
I have not used it myself, but you might find the dist() function in the
proxy package to be useful.

Dear all,
Given vectors "x" and "y", I would like to compute the proportion of
entries that are equal, that is, mean(x == y).
Now, suppose I have the following matrix:
n <- 1e2
m <- 1e4
X <- matrix(sample(0:2, m*n, replace = TRUE), ncol = m)
I am interested in calculating the above proportion f
Thanks Simon!
That worked!
I did not constrain my k as you suggested, but when I saw my results, my
degrees of freedom are not larger than 1, the REML is negative and all
covariates are not significant (what it does not make sense). Is there
something wrong?
Here's the results of summary (a2)

Rodrigo,
OK, it looks as if your mgcv help files/manual are somehow out of sync
with the package version you have loaded. 'betar' is only available from
mgcv 1.8. If you update to the current mgcv from CRAN then this problem
should be solved.
best,
Simon
ps. beta regression is only availabl
Can you give the result of typing
sessionInfo()
in the session where this happens, please?

Dear list,
I have read several posts on this topic. I would use the same
methodology as proposed

Hi ,
SO i have been on a role of asking simple questions lately. So much for
feeling like im getting this R business.
I wrote a script 2 weeks ago that utilized "proportion" to turn values in a
table (from "table") into proportions to then graph. I now get an error
that proportion is not a

Dear R-help,
I would like to compute the variance for the proportion of treatment
effect by a surrogate in a survival model (Lin, Fleming, and De
Gruttola 1997 in Statistics in Medicine). The paper mentioned that
the covariance matrix matches that of the covariance matrix estimator
for the margin
