Delete rpart/mvpart cross-validation output
Dear all,
I was wondering if there is a simple way to avoid printing the multiple
cross-validation automatic output to the console of recursive partitionning
functions like rpart or mvpart. For example...
> data(spider)
>
mvpart(data.matrix(spider[,1:12])~herbs+reft+moss+sand+twigs+water,spider,xv="1se",xvmult=100)
*X-Val rep : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Error in mvpart example
Dear all,

require(mvpart)
data(spider)
fit3 <- rpart(gdist(spider[,1:12],meth="bray",full=TRUE,sq=TRUE)~water+twigs+reft+herbs+moss+sand,spider,method="dist") #directly from ?rpart
summary(fit3)
...which returned the following:
Error in apply(formatg(yval, digits - 3), 1, paste, collapse = ",", sep = "") :

This seems to be a problem with the cross...

I am analyzing plant communities with the function mvpart, using a

[PATCH 0/5] btrfs: lz4/lz4hc compression
WARNING: This is not compatible with the previous lz4 patchset. If you''re using
experimental compression that isn''t in mainline kernels, be prepared to backup
and restore or decompress before upgrading, and have backups in case it eats
data (which appears not to be a problem any more, but has been during
development).
These patches add lz4 and lz4hc compression
