implicit loop for nested list
Is this what you want: ## This cbinds all the 2 matrix components of mysim ## producing a 2 x 20 matrix do.call(cbind,lapply(mysim,`[[`,1)) ## Change the 1 to a 2 to cbind the other components. Cheers, Bert Tha On Thu, Jan 26, 2023 at 7:33 PM Naresh Gurbuxani <

I am looking for a more elegant way to write below code.
#Simulation results have different dimensions
mysim <- lapply(1:10, function(y) {
two.mat <- matrix(rnorm(4), nrow = 2)
four.mat <- matrix(rnorm(16), nrow = 4)
list(two.mat = two.mat, four.mat = four.mat) #results with different
dimensions
})
#Collect different components of simulation results
#Is it possible to do this with implicit loops?
mat2 <- matrix(nrow = 2, ncol = 1)
mat4 <- matrix(nrow = 4, ncol = 1)
for (mat.list in mysim) {
mat2 <- cbind(mat2, mat.list[["two.mat"]])
mat4 <- cbind(mat4, mat.list[["four.mat"]])
}
mat2 <- mat2[,-1]
mat4 <- mat4[,-1]
