Hi
I want to add a row to a "data.table" in each round of a for loop.
"rbind" seems to be a inefficient way to implement this.
How would you do this? The "slow" solution:
library(data.table)
Rprof("test.out")
dt <- data.table()
for (i in (1:10000)) {
# algorithm that generates a list with different values,
# but same key-names, each round, for example
l <- list(A=1,B=2,C=3,E=4,F=5)
dt <- rbind(dt,l) # very slow :(
}
Rprof(NULL)
summaryRprof("test.out")
thx
Christof
