Merge two ggplots
Hello everyone.
I am using ggplot and I need some help to merge these two plots into one.
plot_CR<-function(x,y,agentid,CRagent){
library(ggplot2)
agent<-CRagent[[agentid]] # To make following expression shorter
ggplot((data.frame(x=CRX,y=CRY,sr=agent$sr)))+
geom_point(aes(x,y,colour=cut(sr,c(0,-10,-20,-30,-40,-50,-60,-70,-80))))+

Find and remove elemnts of a data frame
Dear all,
I have a data frame that is created like that
data.frame(x=CRX[-1],y=CRY[-1],z=CRagent[[1]]$sr)
the output looks like
45 116 162 -30.89105988567164
46 128 79 -42.66296679571184
47 180 195 -30.45626175641315
48 114 83 -45.26843476475688
49 118 73 -46.85389245327003
How can I select only the rows that their third column is higher that -45?
This will return the following

More efficient alternative to combn()?
Hi,
i am working on a problem where i need to compute the products of all
possible combinations of size m of the elements of a vector. I know that
this can be achieved using the function combn(), e.g.:
> vector <- 1:6
> combn(x = vector, m = 3, FUN = function(y) prod(y))
In my case the vector has 2000 elements and i need to compute the values
specified above for m = 32. Using combn() i

smbclient's tar_re_search broken?
Hi all,
My old and stable backup script don't work anymore.
It's based on smbclient's tar command using crX parameters for creating
archive, excluding files based on basic regular expressions.
The box is running Fedora core 2, fully updated:
kernel-2.6.8-1.521
samba-common-3.0.7-2.FC2
samba-client-3.0.7-2.FC2
The error is easily reproducible:

that was a stupid answer, sorry, i did read it correctly.
post your smb.conf (sanitized) so we can have a look what we are talking about.

Combine vectors in order to form matrixes with combn
Hello!
I've a problem with the combn function and a set of vector. I
would like to make a simple combination where, instead of scalars, i
would like to combine vector, in order to form matrixes.
In other
words, i have nineteen 6-items vectors (for example coef1-coef19), that
i would like to combine in n!/k!(n-k)! 6x6 matrixes.
I tried with a

Matrixes inside matrixes
Hello everyone,
Could you please help me find out if R supports matrixes inside matrixes?
This is what I would like to do
I have an area map of humidity per km. I would like at every cell to keep also
information about the height of this area, the current temperature etc.
Is something like that supported?
I would like to thank you in advance for your help

efficient conversion of matrix column rows to list elements
Hi List,
I'm hoping to get opinions for enhancing the efficiency of the following
code designed to take a vector of probabilities (outcomes) and calculate a
union of the probability space. As part of the union calculation, combn()
must be used, which returns a matrix, and the parallelized version of
lapply() provided in the multicore package requires a list. I've found that

Error: Can not handle categorical predictors with more than 32 categories.
Hi All,
My question is in regards to an error generated when using randomForest
in R. Is there a special way to format the data in order to avoid this
error, or am I completely confused on what the error implies?
"Error in randomForest.default(m, y, ...) :

print-show-display a matrix
Hello.
I want to print the value a matrix has. The matrix's size is not too big
(100*100 cells). I tried print(matrixname) but as it does not fit very well on
my screen R splits it into several small matrixes that do overflow my screen.
IS it possible somehow to display this matrix as one (even if this needs to go
fullscreen) . There might be some function for that like plot cells or

How two compare two matrixes
Dear all I have two 10*10 matrixes and I would like to compare theirs contents. By the word content I mean to check visually (not with any mathematical formulation) how similar are the contents.
I also know edit that prints my matrix in the scree but still one edit blocks the prompt to launch a second edit() screen.
What is the best way to compare these two matrices?
I would like to thank you

Efficient calculation of partial correlations in R
Hello,
I'm looking for an efficient function for calculating partial correlations.
I'm currently using the pcor.test () function, which is equivalent to the
cor.test() function, and can receive only single vectors as input. I'm
looking for something which is equivalent to the cor() function, and can
receive matrixes as input (which should make the calculations much more
efficient).

efficient list indexing
Hello everyone,
I need some help with lists inside lists (a good way to emulate a struct)\
Assume that there is a small list called fred:
fred <- list(happy = 1:10, name = "squash")
and a big list called bigfred that includes fred list 5 times
bigfred <- rep(fred,5)
Is it possible somehow to index all these sublists(fred) inside bigfred with a
more direct way like this:

Gini's Importance Value Variable = Inf
Hi All,
In the script below, the importance measure for column 4 (ie
MeanDecreaseGini) indicated "Inf" for V7.
Running the getTree command showed that "V7" had been selected at least
twice in one of the trees for Random Forest. So the "Inf" command was
not generated as a result of dividing the sum of the decreases by 0.

Make R 'Beep'

I would like to ask you if R can produce any kind of sound. It would be useful when code execution stops R to notify me by playing some sound.
Is that possible in R?
