Examples

start <- as.Date("2012-01-01")
data <- loadCommunesCHdata()
## Get all the communes "Fusion"  [A] + [B] = [C]
# get the ID of the new communes created 
ginimut <- data[which(data$GINIART == 21 & data$GINIDAT >= start),'GINIMUT']
# get all the communes "radiated" radiée/suprimée
data[which(data$GFINMUT %in% ginimut & data$GFINART == 29),]
# Get for each commune created between start & end time, the GBFSNR of the merged communes
result <- lapply(ginimut, function(i) {
  # get the nr and name of the created commune
  nr_name <- data[which(data$GINIART == 21 & data$GINIMUT == i), c('GBFSNR', 'GNAME')]
  # get the nr of the radiated communes
  radiatedN <- data[which(data$GFINART == 29 & data$GFINMUT == i),'GBFSNR']
  if(identical(radiatedN, integer(0))) {
    list(nr = unlist(nr_name[1]), name = unlist(nr_name[2]), radiated = NULL)
