safeSubset R Documentation
subset a dataframe
Description
takes potentially unsafe row and column filters and evals them in the context of the dataframe.
It takes the following precautions:
* it takes a snapshot of all the envirnoments before the execution and deletes any new objects it finds after the execution
* it locks all environments before the execution, so no existing object can be modified
Usage
safeSubset(df, row.filter = TRUE, col.filter = TRUE)
Arguments
df
a dataframe
row.filter
a character, the filter for rows (as in '[')
col.filter
a character, the filter for columns (as in '[')
