What appears to be happening is that you are plotting
all the data sets but all the lines () are being
plotted outside the original plotting frame. If you
just plot out$a with axes=TRUE you will see what the y
coordinates are. You need to explicitly set the ylim
values.
There is a mockup of what I think you want to do.
------------------------------------------------------
a <- 5:7
b <- c(.005,.009,.01)
c <- c(.05,.08,.12 )
out <- data.frame(a,b,c); out
plot_colors <- c("blue","red","forestgreen","yellow")
plot(out$a, log="y", type="l", col=plot_colors[1],
ylim=c(.0001, 8),
xlab="tittle_x_axe", ylab="title_y_axe", cex.lab=0.8,
lwd=2, xaxt='n')
axis(1, at=1:3)
lines(out$b, type="l", pch=1, lty=1,
col=plot_colors[2])
lines(out$c, type="l", pch=2, lty=2,
col=plot_colors[3])
