You miss Yihui's point I think: roxygen2 will generate the (Namespace

directives to put in your comments).

diff() does not work on data.frames so you need to give it a column
from the data.frame, as a vector.
diff(data.frame(P=c(1,2,3,5,7,11,13,17))$P)
[1] 1 1 2 2 4 2 4
You get different errors for multi- and single-column data.frames

Hi Somayya,
When you perform a t-test on two sets of numeric values, the answer
you get tells you how likely it is that those two sets of numbers came
from the same distribution. What most people are interested in is
whether the means of those two distributions are different. Let's see,

Greetings Peter and Jeff,
Thanks for this information. Will try these type of analyses in SAS.
Sure they are doable in R, but developing a procedure is difficult.
Alan Agresti gives a cookbook SAS method in An Introduction to
Categorical Analysis.
Thanks,

Shouldn't your "[:digit:]" be "[[:digit:]]"?

Using R is a grate advantage, thanks for your work.
Using regex under R 3.1.1, Debian 8.6 jessy works fine.
str_detect("16-03-08", "[:digit:]{2}")
[1] TRUE
str_detect("16-03-08", "[0-9]{2}")
[1] TRUE
runing the same code under R 3.3.2 backport, Debian 8.6 jessy gives a
different result. This is

I used roxygen2 v5.0.1 to document my package, and all was ok. I have

You need the leading zeros, and 'numerics' just give the number without
leading zeros. You can use 'sprintf' for create a character string with
the leading zeros:

Hi Nabila,
This is because you ask to create a sequence with seq(), which does not
make much sense with non numeric data. That's why R trims the 0.
One alternative would be:
seq2 <- paste("DQ0", seq(60054, 60060), sep = "")
Would that work for you?
HTH,
Ivan

What does the function ksmooth() to correct bias? Reading articles gives me the
formula:
\frac{$B-t(B^n_{i=1}K_h(x-x_i)y_i}{$B-t(B^n_{j=1}K_h(x-x_j)}
For the Nadaray-Watson estimator. The same formula is stated in the
documentation for the function:

Hello useRs,
I am announcing the release of my first package, usmap (

"usmap" is a package to aid in the creation of US choropleths that include
Alaska and Hawaii. It is still in its early stages (v 0.1.0) but I hope to
improve it with added functionality
