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)
