r - 重新组织数据框

Question

我想重新组织我的数据框。我只是想将最后一列移到第一位，其余列以相同的顺序离开。我使用函数子集来做到这一点。它有效，但如果我有 100 列左右，那会很痛苦。有没有更简单的方法呢？

tbl_comp <- subset(tbl_comp, select=c("Description","Meve_mean","Mmor_mean", "Mtot_mean", "tot_meanMe", "tot_meanMm", "tot_sdMe", "tot_sdMm", "Wteve_mean", "Wtmor_mean", "Wttot_mean", "tot_meanwte", "tot_meanwtm", "tot_sdwte", "tot_sdwtm"))

Answer 1

尝试这个

tbl_comp <- subset(tbl_comp, select=c(Description , Meve_mean:tot_sdwtm))

Answer 2

tbl_comp <- cbind(tbl_comp[ncol(tbl_comp)], tbl_comp[-ncol(tbl_comp)])

会成功的。
