Please, I wonder if someone knows how to add the
less than or equal to symbol in the plot generated by the code below:
var1<-c('age <= 3','age <= 7','age <= 10','age <= 11','age <= 20','age <=
25','age <= 30','age <= 45','age <= 50','age < 55','age >= 55')
var2<-c(3.8,5.4,3.7,3.8,5.9,6.4,7.2,8.4,10.5,1.3,0.7)
table1<-data.frame(var1, var2)
plot(x=table1$var2,y=1:11,xlim=c(0,20),pch=20)
text(x=table1$var2,y=1:11,table1$var1,pos=4)
title(x=15,y=5,expression("how to substitute the < = with the " <=
"symbol"),font=5)
Please, note that the data must come from a table (not manually fed in a
text command)
I received help yesterday and learned a fix using
\u2264, eval, parse, and sprintf but the symbols generated by this fix are
not exported to an .EPS file
Kind regards,
