Hello,
how to merge a data.frame and a matrix by one column in the data.frame and
rownames of the matrix?
df <- data.frame(col1=c("kk","yy","kk"),col2=c(6,4,3))
> df
col1 col2
1 kk 6
2 yy 4
3 kk 3
m<-matrix(c(3,8,56,9), nrow=2, dimnames = list(c("aa","kk"),c("col1","col2")))
> m
col1 col2
aa 3 56
kk 8 9
the result is expected as
col1.x col2.x col1.y col2.y
kk 6 8 9
kk 3 8 9
