Based on a related post on one of my favorite python-lists I remembered, that I wrote a similar snipplet some time ago.

So if you want to dump your whole MySQL database to csv-files you can recycle the following code:

require(RMySQL)
m<-MySQL()
summary(m)
con<-dbConnect(m, dbname = "YOURDB", host="localhost", port=8889, user="YOURUSER", pass="YOURPASS", unix.sock="/Applications/MAMP/tmp/mysql/mysql.sock") # in case you are using MAMP 
tables<-dbListTables(con)
 
for (i in 1 : length(tables)){
temp<-(dbReadTable(con, tables[i]))
write.table(temp, tables[i], row.names=F)}
