using loop to create a new list from previous list in r -

-

i executing function (computemodules{bipartite}) yields different results every time run. want iterate execution 100 times. function's output consists of list several slots. have extract matrix 1 of these slots (@modules) , subset obtain rows i'm interested in. later using these rows select positions of vector. in end, want obtain 100 lists many sublists rows subsetted in each iteration.

simulated @modules:

n1 <- structure(c(1, 1, 1, 2, 2, 2, 2, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 0, 1, 0, 2, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, 0, 3, 0, 4, 0, 0, 0, 0, 4, 0, 5, 0, 0, 0, 0, 5, 0, 6, 0, 0, 0, 0, 6, 0, 7, 0, 0, 0, 0, 7, 0, 8, 0, 0, 0, 0, 8, 0, 9, 0, 0, 9, 0, 0, 0, 10, 0, 0, 10, 0, 0, 0, 11, 0, 0, 0, 11, 0, 12, 0, 0, 12, 0, 0, 0, 0, 13, 0, 0, 0, 0, 13, 14, 0, 0, 14, 0, 0, 0, 0, 15, 0, 0, 0, 0, 15, 16, 0, 0, 16, 0, 0, 0, 17, 0, 0, 17, 0, 0, 0, 0, 18, 0, 0, 0, 0, 18, 0, 19, 0, 0, 0, 0, 19, 20, 0, 0, 20, 0, 0, 0, 0, 21, 0, 0, 21, 0, 0, 0, 22, 0, 0, 22, 0, 0, 0, 23, 0, 0, 0, 23, 0, 0, 24, 0, 0, 24, 0, 0, 0, 25, 0, 0, 25, 0, 0, 0, 26, 0, 0, 0, 26, 0, 0, 27, 0, 0, 27, 0, 0, 0, 28, 0, 0, 0, 28, 0), .dim = c(7l, 30l))   n2 <- structure(c(1, 1, 2, 2, 2, 2, 2, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 2, 0, 0, 0, 0, 2, 0, 3, 0, 0, 3, 0, 0, 0, 4, 0, 0, 4, 0, 0, 0, 5, 0, 0, 5, 0, 0, 0, 6, 0, 0, 6, 0, 0, 0, 7, 0, 0, 7, 0, 0, 0, 8, 0, 0, 8, 0, 0, 0, 9, 0, 0, 0, 0, 9, 0, 10, 0, 0, 0, 0, 10, 0, 11, 0, 0, 0, 11, 0, 12, 0, 12, 0, 0, 0, 0, 0, 13, 0, 0, 13, 0, 0, 14, 0, 14, 0, 0, 0, 0, 0, 15, 0, 0, 15, 0, 0, 16, 0, 16, 0, 0, 0, 0, 17, 0, 17, 0, 0, 0, 0, 0, 18, 0, 0, 18, 0, 0, 0, 19, 0, 0, 19, 0, 0, 20, 0, 20, 0, 0, 0, 0, 0, 21, 0, 0, 0, 0, 21, 0, 22, 0, 0, 0, 0, 22, 0, 23, 0, 0, 0, 23, 0, 0, 24, 0, 0, 0, 0, 24, 0, 25, 0, 0, 0, 0, 25, 0, 26, 0, 0, 0, 26, 0, 0, 27, 0, 0, 0, 0, 27, 0, 28, 0, 0, 0, 28, 0), .dim = c(7l, 30l))

my code:

e <- 1:30 nr=2 n=list(n1, n2); comp2=list(); u=list(); m=list() for(i in 1:nr){ m[[i]] <- n[[i]][,-c(1,2, (ncol(n[[i]])-5):ncol(n[[i]]))] # select columns of interest comp2[[i]] <- which(n[[i]][,1]==2) # subset values of column 1 (total 5) for(j in 1:length(comp2[[i]])){ # here want create 2xlength(comp2[[i]]) list u[[i]] <- e[unlist(m[[i]][comp2[[i]][j],])] # create list u selecting values of e } }

i obtain:

> u [1]] > e[unlist(m[[1]][comp2[[1]][1],])] [1] 12 14 16 17 20 > e[unlist(m[[1]][comp2[[1]][2],])] [1]  2  9 10 21 22 > e[unlist(m[[1]][comp2[[1]][3],])] [1] 11 > e[unlist(m[[1]][comp2[[1]][4],])] [1]  1  3  4  5  6  7  8 13 15 18 19 [[2]] > e[unlist(m[[2]][comp2[[2]][1],])] [1] 12 14 16 17 20 > e[unlist(m[[2]][comp2[[2]][2],])] [1] integer(0) > e[unlist(m[[2]][comp2[[2]][3],])] [1]  1  3  4  5  6  7  8 13 15 18 19 > e[unlist(m[[2]][comp2[[2]][4],])] [1] 11 > e[unlist(m[[2]][comp2[[2]][5],])] [1]  2  9 10 21 22

but code overwrites output of each iteration , keeps last 1 each list:

> u [[1]] [1]  1  3  4  5  6  7  8 13 15 18 19 [[2]] [1]  2  9 10 21 22

how can desired list of lists?

"p4", "p5", "p6", "p7", "p8", "p9", "p10"), class = "data.frame", row.names = c(na, -40l))

adapted code:

pl <- 40 # number of columns deleted in tmp@modules eox <- unlist(dimnames(data)) # names of rows , columns l <- vector("list", 2l) # lists (i in 1:length(l)) { tmp <- computemodules(data) tmp <- tmp@modules ss1 <- which(tmp[,1]==1) # subsetting module 1 tmp <- tmp[,-c(1,2,(ncol(tmp)-pl+1):ncol(tmp))] # delete columns of no interest (j in 1:length(ss1)) {    l[[i]] <- eox[tmp[ss1[j],]] # rows of tmp meet subsetting conditions; use each row select position in eox. then, create many sublists rows in tmp3 , assign l[[i]] }

everything works fine last line of code not yield desired output , last loop overwrites previous ones. perhaps desired output obtained more directly?

perhaps pseudocode?

l <- vector("list", 100l) (i in 1:length(l)) {     tmp <- computemodules(...) # specific arguments     tmp <- tmp@modules # slot want     tmp <- subset(tmp, ...) # subsetting requirements     l[[i]] <- tmp # put piece/answer want list }  res <- unlist(l)

or maybe need loop on l again , different stuff. alternatively, if did this: l[[i]] <- computemodules(...) list of lists.

edit: small version data

library('bipartite') data(small1976) l <- vector("list", 1l) (i in 1:length(l)) {     tmp <- computemodules(small1976) # specific arguments     tmp <- tmp@modules # slot want     tmp <- subset(tmp, ...) # subsetting requirements     l[[i]] <- tmp # put piece/answer want list }

without subsetting, tmp numeric matrix. need it?

edit 2: if right, overthinking subsetting process.

library("bipartite") eox <- unlist(dimnames(data)) pl <- 40 l <- vector("list", 1l) (i in 1:length(l)) {     tmp <- computemodules(data, deep = true)     tmp <- tmp@modules # slot want     tmp <- tmp[,-c(1,2,(ncol(tmp)-pl+1):ncol(tmp))] # delete columns of no interest     ss1 <- which(tmp[,1]==1) # subsetting module 1     l[[i]] <- eox[ss1] # put piece/answer want list     }

gives, l:

[[1]] [1] "1" "2" "4"

but there must random fitting going on, different answers on different runs.
