Hi all, thanks for your reply.... But I have to make one thing clear that there are no errors in programming...I assure that to you, because I have extracted the data many times from the same program...
The problem is with the connection of R with Bloomberg, sometimes the data is not fetched at all and so I get the below errors...It is mainly due to some network jam problems and all... Could anyone suggest me how to refresh R, or how to always make sure that the data is downloaded without any errors for each loop? I tried with Sys.sleep() to give some free time to R...but it is not successful always... Could anybody help me out?

It looks as you need to convert cdaily to the correct class (same class as d_mer). Don't forget to use traceback() when debugging your program. You code could use some tweaking. Don't be afraid to add spaces and indentation. That will make you code a lot more readable. I noticed that you have defined some variables within your function (lent, t). This might lead to strange behaviour of your function, as it will use the global variables. Giving a variable the same name as a function (t) is confusing. t[2] and t(2) look very similar but do something very different. Sometimes it pays off to covert for-loop in apply-type functions.

This is my download function... download<-function(fil) { con<-blpConnect(show.days=show_day, na.action=na_action, periodicity=periodicity) for(i in 1:lent) { Sys.sleep(3) cdaily<-blpGetData(con,unique(t[,i]),fil,start=as.chron(as.Date("1/1/199 6", "%m/%d/%Y")),end=as.chron(as.Date("12/28/2006", "%m/%d/%Y"))) #Sys.sleep(3) if(!exists("d_mer")) d_mer=cdaily else d_mer=merge(d_mer,cdaily) rm(cdaily) } dat<-data.frame(Date=index(d_mer),d_mer) dat$ABCDEFG=NULL path1<-paste("D:\\SAS\\Project2\\Daily\\",fil,"_root.sas7bdat",sep="") path2<-paste("D:\\SAS\\Project2\\Daily\\CODEFILES\\",fil,".sas",sep="") sasname<-paste(x1,fil,"'",sep="") write.foreign(dat,path1,path2,package="SAS",dataname=sasname) blpDisconnect(con) } for(j in 1:lenf) { fname<-paste("D:\\SAS\\Project2\\Daily\\",filename[j],"_root.sas7bdat",s ep="") Sys.sleep(600) if(!file.exists(fname)) download(fil=filename[j]) } And lent=58 and lenf=8... 8 text files will be generated in this process if the program would have run properly, and each would be of size 4,000 KB. The error message I get if the program is not run is: Error in dimnames(x) <- dn : length of 'dimnames' [2] not equal to array extent In addition: Warning message: Index vectors are of different classes: chron chron dates in: merge(d_mer,cdaily) Please could any one help on this? -----Original Message----- From: Sarah Goslee [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 13, 2007 7:09 PM To: Shubha Vishwanath Karanth Cc: [email protected] Subject: Re: [R] Fatigued R Hi Shubha, Perhaps you haven't gotten any help because you haven't provided a reproducible example, or even told us what you are trying to do (specifically) or what errors you are receiving. Frankly, your problem statement doesn't make any sense to me, and I can't provide advice without more information. As the footer of every email says: PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
