我正在尝试使用pivot_longer来延长我的数据框，但我不需要它很长，并且希望输出多个“值”列。

例子：

df <- tibble(\n  ids = c("protein1", "protein2"),\n  mean.group1 = sample(1:1000, 2),\n  mean.group2 = sample(1:1000, 2),\n  se.group1 = sample(1:10, 2),\n  se.group2 = sample(1:10, 2)\n)\n\ndf\n# A tibble: 2 \xc3\x97 5\n  ids      mean.group1 mean.group2 se.group1 se.group2\n  <chr>          <int>       <int>     <int>     <int>\n1 protein1         763         456         6         4\n2 protein2         820         624         4         7\n

我想要的输出是：

df2 <- tibble(\n  ids = c("protein1", "protein1", "protein2", "protein2"),\n  mean = c(df$mean.group1[1], df$mean.group2[1], df$mean.group1[2], df$mean.group2[2]),\n  se = c(df$se.group1[1], df$se.group2[1], df$se.group1[2], df$se.group2[2]),\n  group = c("group1", "group2", …
