[R] rbind

[Petr Pikal]

Hi

if you are really sure that all columns in all data frames you want 
to stack are the same type and in the same position just make names 
in all data frames equal.

> df1<-data.frame(rnorm(10), rnorm(10))
> df2<-data.frame(rnorm(10), rnorm(10))
> names(df2)<-c("a", "b")
> df1
    rnorm.10. rnorm.10..1
1  -0.1645236   0.3981059
2  -0.2533617  -0.6120264
...
> df2
             a            b
1   2.40161776  0.475509529
2  -0.03924000 -0.709946431
...
> rbind(df1,df2)
Error in match.names(clabs, names(xi)) : names don't match previous 
names:
        a, b

> names(df1)<-names(df2)
> rbind(df1,df2)
              a            b
1   -0.16452360  0.398105880
2   -0.25336168 -0.612026393
