getting started with R and mysql
I have a mysql database I installed on my Ubuntu server, and I'm trying to figure out how to access and analyze it from a Win XP machine running R 2.15.1. I thought that RMySQL was the way to go. (Is there an easier way?) I tried to follow the instructions at http://www.r-bloggers.com/installing-the-rmysql-package-on-windows-7/ so I installed mysql-installer-community-5.5.27.0.msi, then set the environment variable MYSQL_HOME, and tried to install RMySQL within R. It failed, as shown below, but I can't see what is wrong. What's missing? If I only want to read tables from the database and work on them in R, is there an easier package? > Sys.getenv("MYSQL_HOME") [1] "C:\\Program Files\\MySQL\\MySQL Server 5.5" > install.packages('RMySQL',type='source') also installing the dependency ?DBI? trying URL 'http://probability.ca/cran/src/contrib/DBI_0.2-5.tar.gz' Content type 'application/x-gzip' length 308395 bytes (301 Kb) opened URL downloaded 301 Kb trying URL 'http://probability.ca/cran/src/contrib/RMySQL_0.9-3.tar.gz' Content type 'application/x-gzip' length 165363 bytes (161 Kb) opened URL downloaded 161 Kb * installing *source* package 'DBI' ... ** R ** inst ** preparing package for lazy loading Creating a generic function for 'summary' from package 'base' in package 'DBI' ** help *** installing help indices ** building package indices ** installing vignettes 'DBI.Rnw' ** testing if installed package can be loaded * DONE (DBI) * installing *source* package 'RMySQL' ... ** package 'RMySQL' successfully unpacked and MD5 sums checked checking for $MYSQL_HOME...
