Dear R-User,
Appreciate any advice on producing combine output from an R loop. Planning to
project the growth (grow) of plant species (sp) from its initia size
(initial_size). Using the follwing example, how can I produce the results
combining the output from 3 iteration. The ouput a2 produce only the last
iteration.
Thanks in advanced for your advice.
---------
a0 <- data.frame(initial_size=sample(30,10),sp=gl(2,5,10),
grow=as.numeric(as.character(gl(2,5,10)))*0.5)
a2<-c(0)
for( i in 1:3)
{
a1 <- a0$initial_size+a0$grow
a2<- cbind(sp=a0$sp,initial_size=a1+i,yr=i)
a2}
a2
