Hello.
Could someone please tell me where this mata code is wrong ? It gives
an error as " unexpected end of line ". I am making some basic mistake
which I can't figure out.
Thank you,
Ashim.
program define keysortrows
version 9
syntax varlist(min=2) , ///
[ ///
key(string) ///
]
marksample touse, strok novarlist
mata _keysortrower("`varlist'", "`key'","`touse'")
end
mata
void _keysortrower(string scalar varlist,string scalar key,string scalar touse)
{
real matrix x
st_view(X,.,tokens(varlist),touse)
st_view(Y,.,tokens(key), touse)
for(i=1;i<=rows(X);i++){
x=(X[i,.]\Y[i,.])
x=sort(x',2)
x=x'
X[i,.]=x[1,.]
Y[i,.]=x[2,.]
}
end
clear
use data
keysortrows(x1 x2), key(k1 k2)
list
