[R] Installing RODBC

[William Deese]

I tried installing RODBC but got the following message:

Checks were yes until the following

checking sql.h usability... no
checking sql.h presence... no
checking for sql.h... no
checking sqlext.h usability... no
checking sqlext.h presence... no
checking for sqlext.h... no
configure: error: "ODBC headers sql.h and sqlext.h not found"
ERROR: configuration failed for package ‘RODBC’
* removing ‘/home/bill/R/x86_64-pc-linux-gnu-library/3.1/RODBC’

Apparently RODBC was there when R was installed, but library() shows
it is not there now, although the DBI package is. Best ideas for
installing RODBC?
