Dear list,
I want to make a plot based on the following information, using the command
plot.
variable A for x axis : temperature (range: -20 degrees to 40 degree)
variable B for y axis : altitude (range: 50 m to 2500 m )
The data below 0 degree of X variable wants to be erased tentatively.
Please kindly advise the command to extract the data ranging from 0 degree
to 40 degrees.
Thank you.
Elaine
