R help - Nov 2015 - ggplot2 different Y axis scales

Hello Everyone,

I'm using the following code to plot sulfate concentrations vs. time for
several groundwater wells at one time.  Normally I need the scales to all
be the same but in the case of sulfate I need to use a different scale for
each well.  This is because some of my wells have very high / wide ranges
(MW04 ranges from 4 - 3,000) where some have very small ranges (MW06 ranges
from 13 - 34).

Is there a way that I can  have qqplot2 automatically scale each well or a
way I could enter a scale range.?  For example I would like MW04 to have a
Y axis scale from 0 - 3,000 and MW06 to have a Y axis scale from 0 - 40

I am using
RStudio version 0.99.484
R i386 3.2.2
ggplott2 ver 1.0.1
in a Windows 7 environment.

Thank you for your time
David Doyle

  geom_point(aes(shape=Detections))  +

  ##sets the colors
  scale_colour_manual(values=c("black","red")) +

  #location of the legend
  theme(legend.position=c("none")) +

  #sets the line color, type and size
  geom_line(colour="black", linetype="dotted", size=0.5) +
  ylab("Sulfate (mg/L)") +
  ##Graph title
  ggtitle("Figure 6-30
          Sandstone Sulfate Time Series")

## does the graph using the Well IDs as the different wells.
p + facet_grid(Well ~ .)
dev.off()

Read the help for facet_grid, in particular about the scale parameter. I
don't think you can individually control it though.
