Hi,
from what I know there is a current GSOC 2016 project proposal.
(but not accepted yet)
https://github.com/rstats-gsoc/gsoc2016/wiki
https://github.com/rstats-gsoc/gsoc2016/wiki/DeepLearnR-tensorFlow-Object-system-for-R
Is that of interest?
Best,
Bernd

Hi All,
I'm new to R and wants to read XML file as R data frame. Is there any package
that could be used for this purpose.
I will really appreciate your response.
Many Thanks and
Kind Regards

You don't have enough closing parentheses.
Using a text editor written for programmers helps a lot because it will
highlight that kind of error.

Check out the XML package for complete information, and the xml2 package
for extracting data from XML.
I don't think you can directly read the XML into a dataframe because of the
hierarchical structure of the data. There are functions to read an HTML
table into a dataframe. I think you have to t

Due to delays in implementing an updated Windows toolchain for CRAN, R Core has
found it unsafe to go with our usual 1-week beta testing period. Combined with
other scheduling issues, we have decided to postpone the transition to 3.3.0 RC
until April 26, with the final release happening on May 3

Maybe it's not the article itself for sale. Sometimes a company will
charge a fee to have access to its knowledge base. Not because it owns all
of the content, but because the articles, publications, etc have been
tracked down and centralized. This is also the whole idea behind paying a

Dear all;
This must have a rather simple answer but haven't been able to figure it
out: I have a data frame with say 2 groups (group 1 & 2). I want to select
from group 1 say "n" rows and calculate the mean; then select "m" rows from
group 2 and calculate the mean as well. So far I've been using a
Dear R-Experts,
Thanks to Prof. Bonnett, I have got an R script working to calculate confidence
intervals around the semipartial correlation coefficients.
Now, I would like to calculate BCa bootstrap CIs using the boot library and the
boot.ci(results, type="all") function. How could I modify my
Your toy code does not reproduce what you describe: mean(toy$diam[1:nsel[i]])
both times selects from elements of group 1. YOu probably want to subset like
toy$diam[toy$group == i]. Also, if there is any real inefficiency here, it is
_not_ because you are executing a for-loop for two iterations.

Hi Pedro,
This may not be much of an improvement, but it was a challenge.
selvec<-as.vector(matrix(c(nsel,unlist(by(toy$diam,toy$group,length))-nsel),
ncol=2,byrow=TRUE))
TFvec<-rep(c(TRUE,FALSE),length.out=length(selvec))
toynsel<-rep(TFvec,selvec)
by(toy[toynsel,]$diam,toy[toynsel,]$group,mean)
The help text for row+colnames {base} states:
"For a data frame, rownames and colnames eventually call row.names
and names respectively, but the latter are preferred."
Why are they "preferred"?
Why is it names(), not col.names()?
I have only ever used names() for vectors - I'm surprised it w
Data frames are lists of columns. The names() function is appropriate for
lists.
It doesn't pay to fall into the trap of thinking that data frames are truly
symmetric between columns and rows, because there is a performance penalty for
accessing rows that is greater than the cost of accessing
Ah, that makes immediate sense.
