R help - Jul 2016 - Is there a way to coerce ggplot into using min & max values for x & y axes?

I?m plotting few dozen variables, doing so because I need to examine them one at
a time.  The range of these variables varies widely.  One can range from -.5 to
.03, another from -600 to +750.

I want both axes to automatically plot from both min and max values for both
continuous variables.

I?ve tried  - stat_summary(fun.ymax=max, fun.ymin=min), but it doesn?t plot to
the min and max values.

This code neither plots to the min/max nor does it create tick marks on either
axis - scale_y_continuous(breaks = c(min(b12.2$myvar), 0, max(b12.2$myvar)))

Has anyone faced this situation before?  I appreciate the help.

Hi Ken,

You can use coord_cartesian() to set axis. Or if it makes sense to your
problem you can facet your plot.

Hope this helps

Hi

If I want to plot several variables in separate plots I usually use  for cycle
something like

pdf("graph.pdf")
for ( i in 1:n) {

p<- ggplot(data, aes(x, data[,i], colour=...))
print(p + geom_point() + ...)
}

dev.off

and maybe add xlim=c(min, max)

Cheers
Petr
