Your point is well made, but to be precise, I think you should talk
about the "type of" an object, not it's mode. mode() is a wrapper
around typeof(), designed (I believe) for S compatibility.

This was a change in tidyr 0.7.0 that is causing a lot of confusion,
so we are preparing tidyr 0.7.1 which will back this change out.
If you want a work around in the meantime, you can express your
operation a bit more elegantly as:
library(tidyr)
df <- data.frame(v1 = 1:5, somestring = 6:10, v3

I think this is more of a problem with the way that you're accessing
the info, than the design of the underlying structure. I'd do
something like this:
attr_default <- function(x, which, default) {
Try this:
ggplot(mydf,aes(x)) +
geom_line(aes(y = y1, colour = "y1")) +
geom_line(aes(y = y2, colour = "y2")) +
scale_color_manual(values = c(y1 = "green4", y2 = "blue2"))
Note that you don't need to use `mydf` and names in the manual scale
should match the values in the aes() calls.

I'm a bit confused what you're trying to accomplish - the mix of
annotate() and geom_text() is confusing. The following code works for

geom_point(colour = "red") +
geom_line(colour = "blue") +

At the top level do:

Then in your functions do

You have two problems:
* geom_line() always draws from right-to-left
* you're defining colour outside of the plot in a very non-ggplot2 way.
Here's how I'd do it:
library(ggplot2)
data <- data.frame(
x = rep(1:4, each = 25),
y = rep(1:25, times = 4),
g = rep(1:4, each = 25)
)
data$x <- dat
I'd recommend reading the ggplot2 book - learning more about how
scales work in ggplot2 will help you understand why this isn't
possible.

ostly focussed on funding people who have the
skills to solve a problem. In the future, we will explore how to
match up people with skills and people with problems.
* Proposals are due Jan 10.
Please let me know if you have any questions!

vjust was always a hack that I never thought should work. The margins
parameter is the correct way to solve this problem as of ggplot2 2.0.0.

It will be included in the next version of devtools - it's totally
do-able, but no one has done it yet.

== is also vectorised, and you're better off with TRUE and FALSE
rather than 1 and 0, so I'd recommend:
colordata$response <- colordata$color == 'blue'

You normally see these errors when compiling on a vm that has very
little memory.

You may want to read http://rpubs.com/hadley/157957, which captures my

You are going to find your life much easier if you:
* Organise your code so it's easier to read
* Use a consistent naming scheme for your variables
* Learn a bit more about how to modify variables succintly
Here's my rewriting of your script to make it easier to see what's going on.
