Hello, I have little doubt, and I do not think that the way I solve the problem is the best way to do it. The following is a small dataset x<-data.frame(city="Barcelona",sales=253639) x<-rbind(x,data.frame(city="Madrid",sales=223455)) x<-rbind(x,data.frame(city="Lisbon",sales=273633)) x<-rbind(x,data.frame(city="Madrid",sales=266535))

Hello, I have two different dataset, and wanted to join the two. For example I have a table of codes of cities, and other with with the codes of travels, [source for the destine]. what he wanted was to have a new data.frame with all the information city<-data.frame(city="Barcelona",cod=1) city<-rbind(city,data.frame(city="Madrid",cod=2))

Hi all, I am using ISOdatetime, and I just found out that when I do ISOdatetime(1995,03,26,2,10,0) (or any other value under minutes or seconds) I get NA This does not happen with the same time in other dates, nor with different hours in the same date. Any hint why this happens? Using R 2.8.1 under ESS/GnuEmacs under Windows XP Pedro -- View this message in context:

Hi user I have a question about export files. I run my program for different countries and different years. For export files I do this in SAS: (1) Path to data files %let teste=C:\Documents and Settings\MEALQ\My Documents; (2) Country code; %let cc=pt; (3) Survey year; %let yy=03; Output in: &teste\&cc\&yy\cc&yy.txt How can I do a similar command in R?

For that I am using dist?or daisy functions, but I am afraid that the message: Error in vector("double", length) : vector size specified is too large, means too much lines. Can anyone suggest me how should I analyse this matrix? Thanks in advance, Diogo Andr? Alagador MNCN,CSIC, Madrid, Spain

There isn't a samba-412 in the storage repo ( http://mirror.centos.org/centos-8/8/storage/x86_64/) as far as I can see (in opposition to samba-411). Am I doing something wrong?

I want to do hierarchical cluster analysis to compare 10 groups of vectors with five vectors in each group (i.e. I want to make a dendogram showing the clustering of the different groups). I've looked into using dist and hclust, but cannot see how to compare the different groups instead of the individual vectors. I am thankful for any help. Anders

HI All: We are trying to figure out a problem that is occurring with a package, and we need a non-NOAA person with a Windows computer with the latest R to test for us what is failing (but works on Macs and Linux from different sites). Part of the problem is there is an Akamai service in between that we feel may be messing up things. To do this you would need to be willing to: 1. install the
