Problem with RBloomberg and xts.

Dear friends!

I'm trying to get some time series with RBloomberg and then merge them
using merge.xts function

the code is the following:

#install.packages(c("RBloomberg","xts"))
library(RBloomberg)
library(xts)
blpConnect()
symbol1<-"OGZD LI Equity"
symbol2<-"LKOD LI Equity"
s<-as.chron("2011-01-10")
e<-as.chron("2011-07-12")
ts1 <- blpGetData(conn, symbol1, "PX_LAST",
start=s,end=e)
ts2<- blpGetData(conn, symbol2, "PX_LAST",
start=s,end=e)

a_ts1<-index(ts1)
b_ts1<-as.double(ts1)
c_ts1<-as.Date(a_ts1)
m1_ts1<-matrix(b_ts1)
aa1_ts1<-as.POSIXct(c_ts1)
a11_ts1<-xts(m1_ts1,aa1_ts1)

a_ts2<-index(ts2)
b_ts2<-as.double(ts2)
c_ts2<-as.Date(a_ts2)
m1_ts2<-matrix(b_ts2)
aa1_ts2<-as.POSIXct(c_ts2)
a11_ts2<-xts(m1_ts2,aa1_ts2)

e1<-merge.xts(a11_ts1,a11_ts2,method="inner")

I've got the following warning messages:

Warning messages:
1: In merge.xts(a11_ts1, a11_ts2, method = "inner") :
  NAs introduced by coercion
2: In merge.xts(a11_ts1, a11_ts2, method = "inner") :
  NAs introduced by coercion

Could you please tell me what I am doing wrong or probably a shorter way
to merge two or more time series, downloaded with RBloomberg and which
may have different number of points?

Thank you in advance!

Kind regards,
Art Simonov,
London.

Art,

The version of RBloomberg on CRAN (and therefore the version you're
using) is very old. Please do

install.packages("RBloomberg", repos = "r.findata.org")

for the most recent version.

Upgrading should help, but if you're still having issues after that
please let us know.

Sorry, that should be:
install.packages("RBloomberg",repos="http://r.findata.org/")
