Description Usage Arguments Value Examples

This function creates a new political group within EU Parliament that is a combination of other parties. This is done by summing the values in each line of several listed columns and then renames the column.

1	newpoligroup(df, chosenparties, poligroupname, keep = c("Country", "Year"))

`df`	The `dataframe` with the data of the political parties to be joined.
`chosenparties`	The `vector` with the party names that will be joined together.
`poligroupname`	The `string` that will give a name to the new group.
`keep`	The columns of the inputted `dataframe` that will be kept. By default, it will be "Country" and "Year".

Returns a dataframe with the columns inputted from argument keep and an extra column with the sum of the columns listed in chosenparties.

Country <- c("Austria", "Belgium", "Bulgaria")
EPP <- c(1,2,3)
SD <- c(1,2,3)
Other <- c(1,1,1)
IN <- c(1,1,1)
df.data <- data.frame(Country, EPP, SD, Other, IN)
newpoligroup(df.data, chosenparties = c("EPP", "SD"), "traditional", keep = "Country")
