Proc plot - log funtion reading as a variable

wha9202 — Fri, 19 Oct 2018 22:01:59 GMT

I am using SAS Studio

variables are fertility and pcturban

I need to graph log(ferility)*pcturban, but SAS is reading log as a variable, which I don't have.

proc plot data=UN112;
	plot log(fertility)*pcturban;
run;
proc reg data=UN112;
	model log(fertility)=pcturban;
run;

Log function does not highlight blue in SAS Studio.

ERROR: Variable LOG not found.

NOTE: The previous statement has been deleted.

ERROR 22-322: Syntax error, expecting one of the following: a name, ;, -, /, :, _ALL_, _CHARACTER_, _CHAR_, _NUMERIC_, {.

ERROR 200-322: The symbol is not recognized and will be ignored.

Do you actually want the TEXT based result from using Proc Plot?

You would have to use a data step to calculate the log.

Or you might try

proc sgplot data=un112;
   scatter x=ferility y=pcturban;
   xaxis  type=log;
run;

Proc Reg also requires the transform done before hand not on a model statement.

Note that proc reg also supports plotting with the Plots= option.

Most of the time when you think something is a keyword and does not highlight in the editor you are either using it incorrectly or it is not valid at all. Most of the time, there are some exceptions.
