问题 I have a list of .wav files my_list : library(seewave) library(tuneR) data(tico) audio <- tico freq <- 22050 breaks <- c(0,0.2,0.4,0.6,0.8) index <- 1:(length(breaks)-1) my_list<-lapply(index, function(i) audio[(breaks[i]*freq):(breaks[i+1]*freq)]) I want too combine all these files into 1 .wav file, but this doesn't work: index <- 1:length(breaks) allf =lapply(index, function(i) bind(my_list[[i]])) And this is too tedious to do since I have hundreds of multiple files to create: allf =bind(my
