Automatically fix column types

Source: R/fix_coltypes.R

Sometimes things that should be numbers get interpreted as strings (e.g. 1 vs. "1"). This function automatically inferred the best match for each column and reformats its column type accordingly.

fix_coltypes(dat)

Arguments

dat

A data.frame.

Value

A fixed data.frame

Examples

dat <- mtcars
dat$cyl <- as.character(dat$cyl)
dat$wt <- as.character(dat$wt)
dat$drat <- as.factor(dat$drat)

dat2 <- fix_coltypes(dat=dat)
