Usage

To read weights and three questions from card 1 from a multicard ASCII polling file and output a csv file, you'll want something like:

weights<- read_rpr(col_positions=c(1),
widths=c(3),
col_names=c('Weights'),
filepath='data.txt')
card1<- read_rpr(col_positions=c(1,2,4), widths=c(1,2,1), col_names=c('Q1','Q2','Q3'), filepath='data.txt', card_read=1, cards=2)
GALLUP<- cbind(weights,card1)
write.csv(GALLUP,file='cnngallup.csv', row.names=FALSE)
