[R] Fatigued R

Hi R,

 

Please solve my problem...........

 

I am extracting Bloomberg data from R, in a loop. R is getting fatigued
by doing this process and gives some errors. I introduced sleep
function. Doing this sometimes I get the results and sometimes not. I
even noticed that if I give complete rest for R (don't open R window)
for 1 day and then run my code with the sleep function, then the program
works. But if I keep on doing this with on R, repeatedly I get errors.

 

Please can anyone do something for this? Is there any function of
refreshing R completely.....Or any other techniques?...I am really
getting bugged with this.......

 

Thanks,

Shubha

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.

[R] Fatigued R

Ohkkk....I will try to do that now....

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?

[R] Fatigued R

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?

Thank you,
Shubha

Dear Shubha,

The error message tells you that the error occurs in the line:
	merge(d_mer,cdaily)
And the problem is that d_mer and cdaily have a different class. 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.

Cheers,

Thierry

The problem with your code is that it doesn't check for errors. See
?try, ?tryCatch. For example:

my.download <- function(forloop) {
  notok <- vector()
  for (i in forloop) {
    cdaily <- try(blpGetData(...))
    if (class(cdaily) == "try-error") {
      notok <- c(notok, i)
    } else {
      #proceed as usual
    }
  }
  notok
}

forloop <- 1:x
repeat {
  ddata <- my.download(forloop)
  forloop <- ddata
  if (length(forloop) == 0) break  #no download errors; stop
}

[R] Fatigued R

Hi all,

So, is there any method to make bbcomm.exe to sleep for sometime...?

I can't be sure what is happening to Shubhak, but I know that
the Bloomberg server bbcomm.exe throws unhandled exceptions in a 
unreproducable and uncatchable way, somewhere in their tcp code. 

It is one of the big frustrations for me in my work. 

Shubhak, I think you will just have to look carefully at what is
returned,
as Bogdan suggested in general, and take action based on that. It may be

that try[Catch] will catch some problems, but other times, you will just
get 
something that is not right, but you can tell since it has the wrong 
structure.
The bbcomm.exe essentially crashes and gets restarted automatically, so
the 
next time you try to get something, it works; so sleeping after an error
is 
a good idea.

HTH,
David
