Hi, there
I am new to R, here is an urgent question.
I want to save several graphs by a for loop. But I don't know how to refer
the variable in the quotes.
Here is my code.
g<-c("g1","g2","g3","g4","g5","g6","g7","g8","g9")
for (u in 1:9) {pdf("g[u]".pdf")
+ plot(1,1, xlim=range(x), ylim=c(-5,5), type='n', xlab ="Femur length
(mm)", ylab = "Z-Score")
+ mtext("g[u]", side = 4)
+ for (i in z) {
+ lines(x,(log(i)-(m[u]*log(x)+c[u]))/r[u])
+ miny<-(log(i)-(m[u]*log(max(x))+c[u]))/r[u]
+ maxx <- exp((log(i)-c[u]+5*r[u])/m[u]);
+ if (miny > -5) {text(max(x),miny+0.3,i)
+ }else {text(maxx+2, -5+0.3,i)}
+ }
+ dev.off()
+ }
In the second line, I want to refer the variable 'g[n]' to the file name
and fifth line i also want to refer the variable as a note. How should I
do? Thank you very much!
