I'd propose an alternative that I think is superior: rely on the semantics
of ... to do the work for you:
f1 <- function(...){
one <- list(...)[['a']]
two <- ...elt(match('a', ...names()))
c(one, two, three(...))

three <- function(a, ...) {

f1(a = 1, b = 2, c = 3)

You're getting confused between the contents of the string and the

It sounds like you might want a rolling join, e.g.

(And data.table has similar functionality which inspired dplyr)

I'm not aware of widespread problems, but it's possible that some
combination of OS, RStudio version, and R version might be causing
problems. Unfortunately I don't think there's enough information in

If this happens again in the future, you might try the development

install.packages("pak", repos = "https://r-lib.github.io/p/pak/dev/";)

pak automatically diagnoses a number of common problems that causes

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
The most likely explanation is you have a new version of dplyr/tibble
and an old version of rlang. Try re-installing rlang.

Your point is well made, but to be precise, I think you should talk

You have two problems:

Here's how I'd do it:

y = rep(1:25, times = 4),

You're going to need to provide some evidence for that charge: dplyr
does not
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
me, and I think might be what you want:
ggplot(ins, aes(td, glucose)) +
geom_point(colour = "red") +
geom_line(colour = "blue") +
annotate("text", x = texdat
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 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) {

You shouldn't be explicitly opening a device in a knitr document. I think
maybe you should post a minimal document so we can figure out what's going
wrong.

It doesn’t appear to me that mpfr was ever designed to handle expressions
as the first argument.

In that case, you need to create a minimal reproducible example and make it
publicly available.

It might be a line break problem - I think you want:

I have also seen this problem on a student's windows machine (with R
3.2.0 and on multiple mirrors). It appeared that the package zip
itself was being corrupted (with an error to the tune of downloaded
file size does not agree with actual file size). The most likely
explanation that I could come up
It's been fixed in the dev version, and I'm planning on submitting to
CRAN in the near future.

You might want to try readxl instead, as it doesn't have any external
dependencies.

You might try the readxl package - it's only available on github but it
reads both xlsx and xls. All going well, it should be on its way to CRAN
next week.

This somewhat simpler rvest code does the trick for me:
library(rvest)
library(dplyr)
i <- 1:10
urls <- paste0('http://games.crossfit.com/scores/leaderboard.php?stage=5',
'&sort=0&division=1®ion=0&numberperpage=100&competition=0&frontpage=0',

Hi John,
Just printing the result gives a good indication where the problem lies:
> frm %>% rowwise() %>% do(MM=max(as.numeric(.)))
Source: local data frame [6 x 1]
Groups:
MM
1
2
3
4
5
6
do() is designed to produce scalars (e.g. a linear model), not
vectors, so it doesn't join t
