List only values from a subset of a subset of list in R
Hi my datastructure is attached.
I need to access just the mean under each [[ element under extra.
I can do this manually individually opt.state[["opt.path"]][["env"]][["extra"]][[1]][["mean"]]
which gives me NA but there's 100 elements like this.
I followed the solution from this problem of : subset of a subset of a list
using this lst <- lapply(opt.state[["opt.path"]][["env"]][["extra"]], function(x) x[["mean"]])
but end up getting two extra columns I don't need :
How do I go about getting just 1-column list with the values?
Cheers
You can unlist(lst) then you will get a vector of 100 mean values. Columns Name and Type would appear for every list object in R when you View them, Or you can use sapply() function which would directly return a vector in this case, instead of a list.
