Or possibly use 'all.equal' rather than
'identical' if the data are floating
point numbers.
Also these are columns, not rows.

Hi, folks,
Suppose the data is as follows:
#######
x=1:10
y=2:11
z=3:12
data1=data.frame(x,y)
data2=data.frame(x,z)
######
In real case, how to check data1$x and data2$x are the same or not? I am
using for-loop to do this.
Is there a quicker way?
all(data1$x == data2$x)
or
identical(data1$x, data2$x)
