RODBC : reading binary data from a TXT field belonging to a PostgeSQL table
...in the TXT field but when I access to the data, the extracted
dataframe is truncated !
Here's the code :
library("RODBC");
##
## 1. Connection to the database
##
ch <- odbcConnect("PostgreSQL30");
##
## 2. Data Storage. I wrote 10000 bytes in the TXT field of the
tabsignal table
##
## RQ : Thanks to the "paste" function, I convert bytes data in
characters for the storage in the TXT field
## and I put one space between every character (cf.
collapse argument) in order to use
## the strsplit function for the extraction.
##...
