lovefuture 我现在有一个list: > apply(matrix(c(1:2),nrow=1),2,generate,train,N,samplematr) [[1]] Kyphosis Age Number Start 1 absent 39.23016 4 2 2 absent 39.95420 4 10 3 absent 71.00000 3 5 [[2]] Kyphosis Age Number Start 1 absent 98.23251 3 11 2 absent 147.99053 3 6 3 absent 132.96757 4 14 list的两部分就如上面。我想将它们按照变量贴合到一起,做成dataframe的形式。 Kyphosis Age Number Start 1 absent 39.23016 4 2 2 absent 39.95420 4 10 3 absent 71.00000 3 5 4 absent 98.23251 3 11 5 absent 147.99053 3 6 6 absent 132.96757 4 14 折腾好久还是不行。。 还请各位高手指教!
