Greetings everyone,
I'm trying to add a specific table or a specific number of rows (e.g.44) to a
table with no success.
This is my basic table
> head(dataA)
year plot spp prop.B DCA1 DCA2 DCA3 DCA4
1 2000 1 a1 0.031079 -0.0776 -0.0009 0.0259 -0.0457
2 2000 1 a2 0.968921 -0.0448 0.1479 -0.1343 0.1670
3 2000 2 a1 0.029218 -0.0776 -0.0009 0.0259 -0.0457
4 2000 2 a4 0.021678 -0.3052 -0.0275 -0.0330 -0.0516
5 2000 2 a5 0.088596 0.0357 -0.0382 0.0171 -0.0471
6 2000 2 a6 0.065033 0.1219 -0.0588 -0.1119 -0.1795
I want, every time that the plot number changes, to add a specific table
(data2) or a specific number of rows (44) underneath.
I've tried several variations of this with no result
for (i in 2:nrow(dataA))
{
ifelse(dataA$plot[i]!=dataA$plot[i-1],tab=data.frame(res[1:i,1:3]),a=1+1)
rbind(as.matrix(dataA[1:i,]),as.matrix(dataB[,])),a=1+1)
}
many thanks
