Problems with memory
...-5.1.20) and it is started by the
command:
Rterm --min-vsize=10M --max-vsize=100M --min-nsize=500k --max-nsize=1M
I've been had problems when executing a loop like:
attach("data.Rdata")
for (i in 1:n)
{
object1<-fun1(data...)
object2<-fun2(...object1)
object3<-fun3(...object2)
object4[,i]<-fun4(...object3)
rm("object1","object2","object3")
}
After few interactions it stops with the message:
"Error: cannot allocate vector of size 7890 Kb
In addition: Warning message:

Looping through R objects with $ operator and tags
...lues in a column to the log of the values
of another column like so:
object$LogDist <- log10(object$Distance)
How do I loop through the objects if I have object1, object2, etc to
perform this function?
object1$LogDist <- log10(object1$Distance)
object2$LogDist <- log10(object2$Distance)
object3$LogDist <- log10(object3$Distance)
I was trying to use the assign and paste functions like so:
for (i in c(1:10))
assign(paste("object",i,"$LogDist"),log10(as.name(paste("object",i,"$LogDist")))
but that didn't work out. It creates objects with whol...

Create R object
...he following:
for (i in 1:length(lst)){
assign(paste("object",i,sep=""),lst[[i]])
}
I wonder if there's a way to avoid this loop?
2.
I want to validate whether all of the "object"s have the same dimension, that is, whether dim(object1)[1]==dim(object2)[1]==dim(object3)[1]& dim(object1)[2]==dim(object2)[2]==dim(object3)[2] is true. How can I do that easily since the length of lst is not fixed?
Thanks.

remove multiple objects starting with same name
Hi,
I'm trying to figure out syntax R function rm() needs to remove all objects
starting with same name. For example, if I have object1, object2, object3,
i want to do an operation similar to UNIX rm object*
Thanks.

Extract Clusters from Biclust Object
...ing a heatmap, it is
possible to specify the cluster to be plotted. However, I'd like to extract
the clusters in this manner:
Cond.1 Cond.2
Gene - value - value
just like drawHeatmap specifies each cluster. Is there a way to extract
single clusters? E.g. like saying "Object at object3", meaning cluster no. 3 of
my biclust object? Unfortunately, the given answers I found in older posts
could'nt help me out...
Any help is strongly appreciated!
Best regards,
Christine

extend validObject to validate any object (shallow and deep validation)
...)
[1] TRUE
Also, here is another (typical) situation where it would be nice to be
able to (recursively) check the validity of the object:
setClass("Collection", representation(things="list"))
mycollection <- new("Collection", things=list(object1, object2, object3))
The problem is that 'validObject(mycollection, complete=TRUE)'
will return TRUE, even if one of the 3 objects stored in 'mycollection'
is invalid. I could implement my own validity method for Collection
objects but that's not a satisfactory solution because it would always
do...
