[GRASS-user] v.in.ascii: specifying longitude

[Rich Shepard]

   I've a large text file of weather data. A sample row of data is:
station|name|lat|lon|elev|date|dapr|evap|mdpr|prcp|sn01|sn03|snow|snwd|sx01|sx03|wesd|wesf
USC00353770|Headworks Portland Water|45.4486|-122.1547|228.0|2005-01-01||||0.59|||0.0|0.0||||

The fourth column is longitude with values such as -122.1547. When I enter
this command:

in.ascii --overwrite \
in=/home/rshepard/projects/oregon/<project_name/data/precipitation/\
clackamas_co_weather_2005_2018.txt out=precip separator=pipe \
columns="station varchar, name varchar, y double precision, x double \
precision,  elev double precision, date varchar, dapr double precision, \
evap double precision, sn01 double precision, sn03 double precision, \
snow double precision, snwd double precision, sx01 double precision, sx03 \
double precision, west double precision, wesf double precision" x=4 y=3 z=5

grass 7.5svn responds with this error:

Number of columns: 18
Number of rows: 113570
ERROR: 'x' column is not of number type

   How do I specify west longitude without an initial '-' or an appended 'W'?
