Dear R Help group I need to run a command line script from within R session. I am not clear how i can acheive this. I tried shell and system function, but i am missing something critical.can someone provide help? My intention is to create a pdf file of a plot in R and then attach existing files from my system as attachment into the newly created pdf file. Any help would be greatly appreciated.. Here is the command line script i want to execute from within R. pdftools -S "attachfiles=C:\test1.pdf" -i C:\test2.pdf -o C:\test4.pdf Regards Vijayan Padmanabhan [[alternative HTML version deleted]]
One way that u might have thought of is to create plot in PDF in R and the use pdftools. Additionally one can also think of running R script using R CMD and then using pdftools in a .sh script file if u r in linux. I am not aware of pdftools capability in R.

Hey Everyone!
I´m a quite new R user .. I found a problem that I'd like to share with you
and help me find a solution.
I have a large txt. file which I opened with read.table command, and what I
understood from many R manuals is that I have a kind of matrix readed with
read.table,
I've used order() to sort my data and now my problem is: I have a variable
that has many repeated values and I would like to operate with the row
indexes of "these repeated values": for example, suppose I have:
var1 var2 … varN
122 nnn1 … 1
213 nnn2 … 2
422 nnn4 … 2
432 … … 3
441 … … 4
500 … … 4
550 … … 4
So I want to obtain a new column where all elements of var1 are added at the
places where varN are repetead ... so for varN=2 the new column correspond
to this element will be 213+422, for varN=4 will be 441+500+550, where there
is no such repeated values obviously there´s nothing to do and varN is the
unique value.
I made a function to do this but is not so good, (I hava a database with
around 1 million rows and 5 columns) actually, this function works for not
so large data:
suma.rep=function(X,Y){
resp=numeric(0)
Z=unique(Y)
for (i in (1:length(Z)))
resp=c(resp,sum(X[which(Y==Z[i])]))
return(resp)}
When I run this function with my large data, R appears calculating and I
think it would take so long to make my new required column.(maybe 4 days)
Question1: I "feel" that maybe there's a command that could help
me to do
this "simple" operation more elegant, I googled it but I couldnt
find... Is
there any such a command?
Question2: Is a good idea to handle large data bases files with R, as in my
example?
Thank you so much for your help.

Thanks a lot Jim, Dennis. Jim, actually where "dots" were I meant "etcetera" or "similar data". ;) My output is close to that one Dennis proposed with function aggregate, but i would like to keep the column var2 and the rest of columns with the unique value corresponding to var1 greatest value, So suppose the example is: var1 var2 … varN 122 nnn1 … 1 213 nnn2 … 2 422 nnn4 … 2 432 nnn5 … 3 441 nnn6 … 4 550 nnn7 … 4 500 nnn8 … 4 The output were: var1 var2 … varN 122 nnn1 … 1 635 nnn4 … 2 432 nnn5 … 3 550 nnn7 … 4 Maybe that´s the reason for what I want to keep the "indexes" where the conditions are satisfied ( unique varN, sum of var1 were varN are the same, and value of var1 that is the greatest relative to the others same-VarN values). Thanks for your help! Chriss Paúl. [[alternative HTML version deleted]]
Accelerated Failure Time Model to Proportional Hazard Form
Greetings R users:
I have been working on a problem for a while and can't seem to get any
result.
I am trying to convert accelerated failure time estimates to proportional form.
I keep getting an error that I can't understand and don't know if it can
be
debugged or not. My code is as follows:
data<-read.csv("repdata.csv")
da<-na.omit(data)
attach(da)
library(survival)
library(rms)
weib1<-psm(Surv(time,ratified)~island+pop+gdppc+fh+nngo+industryemplimp+icrgfromper+ngoicrgfromper+industryemplimpicrgfromper,
data=da, dist="weibull",init=NULL, scale=0,
control=survreg.control(maxiter=1000))
print(weib1)
f.ph<-pphsm(weib1)
However, after running the last line of code, I get the following:
Warning message:
In pphsm(weib1) :
at present, pphsm does not return the correct covariance matrix
Any suggestions will be greatly appreciated!! My data is attached.
Thanks in Advance
