munge: Munge

In brooke-watson/thesis: Functions for my senior thesis in Epidemiology at LSHTM

Description

Quick and dirty simple munging for data frames with mostly character data.

Usage

munge(df)

Arguments

df	matrix or data table

Details

Note - if this throws the error "Error in FUN(X[[i]], ...) : invalid multibyte string 203", you've got some weird characters in your dataset. Add ' fileEncoding="latin1 ' to the end of your read.csv line for the data frame that you read in.
