You are more likely to get a helpful response if you provide a
reproducible example - without that I can only guess that you need to
use approx so you get y values at same x values.

# plyr
plyr is a set of tools for a common set of problems: you need to
__split__ up a big data structure into homogeneous pieces, __apply__ a
function to each piece and then __combine__ all the results back
together. For example, you might want to:
* fit the same model each patient subsets of
# testthat
Testing your code is normally painful and boring. `testthat` tries to
make testing as fun as possible, so that you get a visceral
satisfaction from writing tests. Testing should be fun, not a drag, so
you do it all the time. To make that happen, `testthat`:
* Provides functions that make
But be careful because class is a character vector (not necessarily a
character vector of length 1)

Hi all,
Are there base functions that do the equivalent of this?
fliptb <- function(x) x[nrow(x):1, ]
fliplr <- function(x) x[, nrow(x):1]
Obviously not hard to implement (although it needs some more checks),
just wondering if it had already been implemented.

Hi Raimund,
To increase your chances of getting help, I'd recommend using the
ggplot2 mailing list, and reducing your example down to the essence of
the problem. For example, the theme components don't affect the

The reshape package will definitely do what you want. Cast will
automatically fill in an missing spots with NAs, and you'll just need
something like the following for your aggregation function:

Hi all,
Does anyone have a version of strsplit that keeps the string that is

x <- "A: 123 B: 456 C: 678"

strsplit(x, "[A-Z]+:")

Any ideas?
