Panel data Spatial weights - spgen

[Chiara Piazzo]

I am trying to generate spatial lagged variable for a panel data using the following code:

gen wvar_exp_75 =.
    forvalues i = 1980(10)2010 {
        spgen yvar if year == `i', lat(lat) lon(lon) swm(exp 0.75) dist(.) dunit(km) app
        replace wvar = yvar_e if year == `i'
        drop yvar_e
}

I am getting the following error: lon() must be within -180 to 180.

But the longitude in my dataset goes from -180 to 179; the variable is stored as double (%9.0g).

My data looks like this:

* Example generated by -dataex-. To install: ssc install dataex
clear
input double(lon yvar) float id double(t p)
-180    .0111553558086116 1 . 0
-180    .0120254920302367 1 . 0
-180    .0153739964407522 1 . 0
-180 3.17805712775318e-06 1 . 0
-180    .0274206289399875 2 . 0
end

Any help/suggestions will be highly appreciated!

Sincerely,

Chiara

Dr. Kondo Keisuke (author of SPGEN) was kind enough to reply to my email. There was a bug, which has been fixed now!
