Converting many dataframe columns to numeric

This function makes it easy to convert many dataframe columns to numeric.

massConvertToNumeric(
  dat,
  byFactorLabel = FALSE,
  ignoreCharacter = TRUE,
  stringsAsFactors = FALSE
)

Arguments

dat

The dataframe with the columns.

byFactorLabel

When converting factors, whether to do this by their label value (TRUE) or their level value (FALSE).

ignoreCharacter

Whether to convert (FALSE) or ignore (TRUE) character vectors.

stringsAsFactors

In the returned dataframe, whether to return string (character) vectors as factors or not.

Value

A data.frame.

Examples

### 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);
