R-users it appears I am leaning on your knowledge once again.  Is there any way to add a vertical line to a histogram and qplot "stacked" plot?  Here is my current attempt:   "qplot" approach attempt: qplot(Run, data = data_dataframe, breaks = breaks, fill = Temperature, main = short_title) + scale_x_continuous("Data") + scale_y_continuous("Freq") +  scale_fill_discrete("Temperature") + scale_fill_manual(values = c(LOW = "blue", AMB ="black", HIGH = "red")) +  geom_abline(v = HighVal, col = "dodgerblue3", lty=&quot...

... variables (characters not numeric) and I need to change from the default qplot colors to the following: Low = Blue Middle = black High = Red   Here is pseudo code of what I have currently:qplot(Run, data = TestData, breaks = hist_breaks, ,            fill = TestData$Temperature,           main = short_title) +           scale_x_continuous("Run, Radians") + scale_y_continuous("Frequency") +           scale_fill_discrete("Temperature")   Thanks for any advice and insights.     [[alternative HTML version deleted]]

Hi All, I've been having a little trouble with creating a loop that will run a a series of t.tests for inspection, Below is the code i've tried, and some checks i've looked at. I've used the get(paste()) idea as i was told previously that the use of the eval should try and be avoided. I've run a single syntax to check that my systax is correct and works without any problems
