Problem with shortestPath in igraph and qgraph
...parameters.
Now I want to know the maximum value of shortest path for each vertex with
discarding the Inf value in short pathes. For this I use the
ShortestPathLengths of centrality function in qgraph. but when I want to
get the maximum the result is wrong. here is my code:
cen<-centrality(Q)
tmp3<-cen$ShortestPathLengths
shp<-matrix(1:ncol(tmp3),ncol(tmp3),1)for(i in ncol(tmp3)){
shp[i,]=max(tmp3[i,][tmp3[i,]!=Inf)}
when I display the valu of shp the result is same as initial value (form
one to ncol). I also test with shortest.paths function. the result was
same. what is my wrong?...

tapply, data.frame problem
Hi R-users,
I'm quite new to R and trying to learn the basics. I have a following
problem concerning the convertion of array object into data frame. I have
made following data sets
tmp1 <- rnorm(100)
tmp2 <- gl(10,2,length=100)
tmp3 <- as.data.frame(cbind(tmp1,tmp2))
tmp3.sum <- tapply(tmp3$tmp1,tmp3$tmp2,sum)
tmp3.sum <- as.data.frame(tapply(tmp1,tmp2,sum))
and I want the levels from tmp2 be shown as a column in the data.frame, not
as row name as it now does. To put it in another way, as a result, I want a
data frame...

Multiple E1s over TDMoE?
When I was trying to run mutiple E1s over TDMoE, the zaptel would
drivers complain about too little memory, whenever I added more than 31
channels. Requesting 62 channels in a dynamic span gave me
... span creation failed: Cannot allocate memory
upon loading the zaptel drivers.
How would you go about running, 8 or 16 say, E1s over TDMoE? Would you
create multiple dynamic spans or just one large

outputting functions in lapply
How come the k is 3 in all of this output?
I expected it to be equal to r.

how to skip a specific value when using apply() function to a matrix?
Hello R experts,
I'd like to studentize a matrix (tmp1) by column using apply() function and skip some specific values such as zeros in the example below to tmp2 but not tmp3. I used the script below and only can get a matrix tmp3. Could you please help me to studentize the matrix (tmp1) without changing the zeros and generate a new matrix tmp2?
Thanks,
Joshua

Wrong UIDs returned from mailbox_transaction_commit_get_uids()
...m is in:
int mailbox_transaction_commit(struct mailbox_transaction_context **t)
{
uint32_t tmp;
return mailbox_transaction_commit_get_uids(t, &tmp, &tmp, &tmp);

It should be:
int mailbox_transaction_commit(struct mailbox_transaction_context **t)
{
uint32_t tmp1, tmp2, tmp3;
return mailbox_transaction_commit_get_uids(t, &tmp1, &tmp2, &tmp3);
}
After this fix it works OK.
