R 将一列展开为多列

R 将一列展开为多列,r,function,dplyr,spread,R,Function,Dplyr,Spread,我有一列“m”,其中包含与一个主题(ID)关联的多个值。我需要将此列中的值分散在5个不同的列中,以获得下面提供的第二个表。我还需要将名称与这些列相关联 f <- read.table(header = TRUE, text = " Scale ID m 1 1 1 0.4089795 2 1 1 0.001041055 3 1 1 0.1843616 4 1 1 0.03398921 5

我的数据集的可能重复项没有列,列中的每个列的名称都要排列。我想将数据集分成五列,然后重命名它们。不过,如果这是不可能的,我会删除我的问题。
