FindReplace: Replace multiple patterns found in a character string column of a data frame

Description

FindReplace allows you to find and replace multiple character string patterns in a data frame's column.

Usage

FindReplace(data, Var, replaceData, from, to, exact = TRUE, vector = FALSE)

Examples

# Create original data
ABData <- data.frame(a = c("London, UK", "Oxford, UK", "Berlin, DE", "Hamburg, DE", "Oslo, NO"),
                     b = c(8, 0.1, 3, 2, 1))

# Create replacements data frame
Replaces <- data.frame(from = c("UK", "DE"), to = c("England", "Germany"))

# Replace patterns and return full data frame
ABNewDF <- FindReplace(data = ABData, Var = "a", replaceData = Replaces,
                     from = "from", to = "to", exact = FALSE)

# Replace patterns and return the Var as a vector
ABNewVector <- FindReplace(data = ABData, Var = "a", replaceData = Replaces,
                     from = "from", to = "to", vector = TRUE)
