Table or file as STDIN to the R Script
Hi all,
I am trying to call the R script/ R Program via my Shell Script. I need to
pass a file to the R script as an argument. When I am trying to do that I am
getting error and only first line of the file is being read. Can you tell me
how should I do that so that it reads the entire file in a R object so that
later I am able to process the matrix operation on that file. It is a tab

optim: abnormal termination in lnsrch (resend)
...ON_IN_LNSRCH
What is optim() trying to say?
What have I to change in my function to make the minimization succeed?
Do you think using BBoptim() instead of optim() changes anything?
Thanks for your help!

Win upgrade pb (virus)

To continue I had to remove the colorspace and ggplot2 packages.
Is it a known problem? What else can I do (except removing the above
packages or changing antivirus)?
Thanks!

Hello I have some strange output from R and I try to understand how R works.
Could you please help me with that?

[1,] 10 1
[2,] 99 98

strange behaviour of median
During some experimentation in preparing R lessons I encountered this
behaviour which I can not explain fully
mat <- matrix(1:16, 4,4)
df1 <- data.frame(mat)
> mean(df1)
X1 X2 X3 X4
2.5 6.5 10.5 14.5
Expected, documented
> median(df1)
[1] 6.5 10.5
Rather weird, AFAIK there shall not be an issue with data frame at least I
did not find any in help page. I tracked it

density() vs. KernSmooth::bkde
...vice when to use denstity() and when the KernSmooth package bkde()

No specific problem to use either one, but I'm curious why there are two
so similar implementations.
Thanks!

Sync data between various PuppetDB instances

cluster) in our datacenter and, eventually, there may be a need to share
*only* a few exported resources between clusters, like a few ssh-keys or
nagios tests.
Is there a mechanism to pull and push some exported resources from one
PuppetDB to another? I guess this could be done with the API, but has
anybody tried it,

How could I terminate a script (without leaving R)?
