RblDownload: Download a file from Bloomberg

Description

Download a generic file from Bloomberg. Use RblFiles to list the files available at Bloomberg. If the file is not available yet (i.e. a request file has just been uploaded), the function waits until the response file is there or the timeout is reached

Usage

RblDownload(file, frequency = 60, timeout = 3600, verbose = TRUE)

Value

character string. Path to the downloaded file. NULL on failure

Arguments

file

character string representing the file to download

frequency

the polling frequency to check if file is available at Bloomberg

timeout

the timeout in seconds

verbose

logical. Should R report extra information on progress?

Examples

if (FALSE) {
# Run RblConnect first

# Build a request file to download the daily closing prices of 
#  EURO STOXX Index from 2005-01-01 to 2015-12-31.
RblRequest <- 
     RblRequestBuilder(
          header = c(FIRMNAME = RblUser(), 
                     PROGRAMNAME = 'gethistory', 
                     DATERANGE = '20050101|20151231'),
          fields = c('PX_LAST'), 
          identifiers = c('SXXE Index')
     )
                                
# Upload the request file
req <- RblUpload(RblRequest)

# Download the response file
out <- RblDownload(req$out)
