R help - Oct 2012 - (no subject)

producing a multi-figure plot, i am try to add beta_1, beta_2,.. beta_9 to
ylab using expression or substitution, but cannot work out like

for (i in 1:9){
   plot(seq(1/m, 1-1/m, 1/m), beta.q[,i], type="l", col=1,
   ylim=range(beta.q),
   xlab="quantile", ylab=expresion(beta[i]))
}

any suggestions will be greatly appreciated.

DL,

Looks like you have a typo in the expression() function.
You had only one "s".
This works for me ...

m <- 10
beta.q <- matrix(rnorm(81), ncol=9)

for (i in 1:9){ 
   plot(seq(1/m, 1-1/m, 1/m), beta.q[, i], type="l", col=1, 
      ylim=range(beta.q), xlab="quantile", ylab=expression(beta[i])) 
   }
