Hi,
use my src.bloomberg.R custom code and try this:

require(xts)

# works with and without suffix 'Index' etc. :)

getSymbols.bloomberg(c('SPX', 'MXWO', 'MXEA'), from = as.Date(begdate))

# PX_LAST: SYM[,4] or Cl(SYM)
sym_data <- merge(SPX[,4], MXWO[,4], MXEA[,4])

tail(sym_data)

zoo_data <- as.zoo(sym_data)
tail(zoo_data)


btw. "to" arg is set as "to = Sys.Date() - 1" (EOD data)

getSymbols.bloomberg <- function(symbols = NULL, exchcode = 'US',
from = Sys.Date() - 365, to = Sys.Date() - 1, env = .GlobalEnv,
auto.assign, verbose, ...)

Best,
Daniel
