Displaying 1 result from an estimated 1 matches for "vnamesj".
Did you mean:
vnames

using the function "expression" with "paste" in a plot
...=array(somedata,c(m,vn,vx))
# producing plots
for (j in 1:vx){
for (i in 1:vn)
{
plot(mydata, type="l", main=expression(paste("Effect of",
vnames[j],"on",vnames[i])), xlab="Lags (quarters)", ylab="Response")
}
}
The title appears as "Effect of vnamesj on vnamesi". Without the function
"expression" title for j=1 and i=2 appears as "Effect of pi on y". The
desired outcome would be return the word "pi" rather than a Greek letter.
Is there any simple way to overcome this situation.
Thank you
