问题
I have the following setup:
- OSX 10.10.2
- PostgreSQL 9.4.1
- R 3.1.3
This answer as of 2011 says that the easiest approach is to use RpgSQL package. But it is removed from the CRAN repository. RODBC mentioned there is available as source, but it fails to configure:
configure: error: "ODBC headers sql.h and sqlext.h not found"
ERROR: configuration failed for package ‘RODBC’
I've also found another package, which could help me - RPostgreSQL, but it fails to compile:
In file included from RS-PQescape.c:7:
./RS-PostgreSQL.h:23:14: fatal error: 'libpq-fe.h' file not found
# include "libpq-fe.h"
^
1 error generated.
make: *** [RS-PQescape.o] Error 1
ERROR: compilation failed for package ‘RPostgreSQL’
Is there any other way to connect R and PostgreSQL?
回答1:
See RODBC to connect to SQL Server on Mavericks
RODBC isn't really supported on OSX.
What I ended up doing is to use RJDBC, which is in CRAN.
Setting up the connection to your data base isn't always easy. But it can be done:
Postgres DB can't connect to R with RJDBC
