It seems, there is a bug in exporting data on starting R session from Gretl
If start a R session with the attached file opened in Gretlvariables l_gdpr_usa and gdpr3 are read as they should be.
gdpr_usa[1] is 99547.54
gdpr3=gdpr_usa/1000
gdpr_usa is read in R as
[1] 142 1 2 5 4 6 7 8 9 15 19 21 26 27 29 31 34 37 36 40 41 43 48
[24] 46 44 50 49 52 54 58 60 64 67 70 68 72 79 81 74 82 83 85 89 91 86 88

[139] 139 135 138 141 143
to the empty text file.
Original header
gdpr_usa
"millions of U.S. Dollars; 1990 prices"
1870 99547.54
was edited to
year gdpr_usa
1870 99547.54
and the text file was imported
If recode the data as cross-section
gdpr3 is read well but
gdpr_usa is read as factor instead of numeric
if type as.numeric(gdpr_usa) we again get
[1] 142 1 2 5 , etc.
