RPostgreSQL Data analytics on PostgreSQL data using R

RPostgreSQL - Data analytics on PostgreSQL data from R

Data analytics on PostgreSQL data using R. Working with R and PostgreSQL for large scale data analytics

Installing RPostgreSQL
install.packages('RPostgreSQL')

compilation terminated. /usr/lib/R/etc/Makeconf:128: recipe for target 'RS-PQescape.o' failed make: *** [RS-PQescape.o] Error 1 ERROR: compilation failed for package 'RPostgreSQL' * removing '/home/boss/R/x86_64-pc-linux-gnu-library/3.1/RPostgreSQL'
RS-PostgreSQL.h:23:26: fatal error: libpq-fe.h: No such file or directory

Solution

RPostgreSQL require libpq-dev.

libpq-dev is a set of library functions that allow client programs (for our case its 'R') to pass queries to the PostgreSQL backend server and to receive the results of these queries.


So we have to install libpg-dev on OS not from R terminal

solai@server# sudo apt-get install libghc-postgresql-libpq-dev

then install RPostgreSQL inside R session
> install.packages('RPostgreSQL')
