massConvertToNumeric.Rd
This function makes it easy to convert many dataframe columns to numeric.
massConvertToNumeric(
dat,
byFactorLabel = FALSE,
ignoreCharacter = TRUE,
stringsAsFactors = FALSE
)
The dataframe with the columns.
When converting factors, whether to do this
by their label value (TRUE
) or their level value (FALSE
).
Whether to convert (FALSE
) or
ignore (TRUE
) character vectors.
In the returned dataframe, whether to return string (character) vectors as factors or not.
A data.frame.
### Create a dataset
a <- data.frame(var1 = factor(1:4),
var2 = as.character(5:6),
stringsAsFactors=FALSE);
### Ignores var2
b <- ufs::massConvertToNumeric(a);
### Converts var2
c <- ufs::massConvertToNumeric(a,
ignoreCharacter = FALSE);
