I'm getting the error, ggplot2 does not know how to deal with data of class tbl_sqlite/tbl_sql/tbl_lazy/tbl
. Does this mean I need to reduce the size of my data or convert it to another format before I can plot it?
dplyr
holds off on actually collecting the data into r until it is explicitly told to. When using dplyr
to query a database, be sure to use collect
at the end of the chain to pull the query result into r as a data frame.
addendum : the dbplot
package now provides helper functions to work with dplyr
& dbplyr
to do some plotting or calculations for intermediate plotting steps in-database
