Exporting tables to RTF?
Greetings.
Yesterday I managed to jury-rig a system to get a table out of R and
import it into Nisus Writer Express (a word processor for Mac OS X).
What I came up with is brittle, since it depends on an AppleScript
script which has to be in a specific location and on no one touching
the computer, since the AppleScript remotely controls Nisus Writer
Express rather blindly and will make

Getting the real names of variables within functions
Greetings.
These days I find myself writing a lot of functions to handle routine
things. One of these is a function to create a scatterplot of
variables and draw a lowessed line so I can get some idea if there's
any relationship between them.
lowessed.plot <- function(x, y)
{ plot(x, y)
lines(lowess(x, y))
}
However, there's a slight problem: the plot axes come out labeled

Dear r-helpers,

Precision in R
Greetings.
I'm trying to recreate in R some regression models I've done in SAS,
but I'm not getting the same results. My advisor suspects this may be
due to differences in precision between R and SAS. Does anyone know
where I can find specifications for R's type double? (It doesn't seem
to be in the R Language Definition.) Thanks in advance for any help
anyone can

httr::content without message
Hi All:
I am using httr to download files form a service, in this case a .csv file. When I use httr::content on the result, I get a message. Since this will be in a package. I want to suppress the message, but haven't figured out how to do so.
The following should reproduce the result:

ggridges help
yes, thanks, and I was getting close to that. One thing I found is the manual says the height is the distance above the y-line, which should be, but doesn't have to be positive. In fact, the time series are estimates of a cycle, and has negative values, which unfortunately are not included in my sub-sample. And the negative values are not handled properly (the series disappears for

RMarkdown question
Hi All:
In creating a R Notebook I know that in the text I can link to a (sub) section by using the command:
[Header 1](#anchor)
and putting the appropriate anchor name at the appropriate header. But can the same be done for code chunks, if the code chunk is named? What I want to do is say that such and such code chunk is an example of how to do something, and have that link to the

Reversing one dimension of an array, in a generalized case
Hi All:
I have been looking for an elegant way to do the following, but haven't found it, I have never had a good understanding of any of the "apply" functions.
A simplified idea is I have an array, say:
junk(5, 10, 3)
where (5, 10, 3) give the dimension sizes, and I want to reverse the second dimension, so I could do:
junk1 <- junk[, rev(seq_len(10), ]

The min_height = -0.25 is there to make it show cycle values down to -1/4.
You may want to change it to -1 so it shows more of the cycle values.

Reversing one dimension of an array, in a generalized case
How about this:
f <- function(a,wh){ ## a is the array; wh is the index to be reversed
l<- lapply(dim(a),seq_len)
l[[wh]]<- rev(l[[wh]])
do.call(`[`,c(list(a),l))
}
## test
z <- array(1:120,dim=2:5)
## I omit the printouts
f(z,2)
f(z,3)

Newbie question: plotting regression models
Greetings.
Is there any way to get R to take a regression model object and draw a
plot of the regression function? How about overlaying that plot over a
scatterplot of the actual data? Thanks in advance for any help anyone
can provide.

Reversing one dimension of an array, in a generalized case
Here is an alternative approach using apply(). Note that with apply() you are reversing rows or columns not indices of rows or columns so apply(junk, 2, rev) reverses the values in each column not the column indices. We actually need to use rev() on everything but the index we are interested in reversing:
f2 <- function(a, wh) {
dims <- seq_len(length(dim(a)))
dims <-

Reversing one dimension of an array, in a generalized case
Thanks again. I am going to try the different versions. But I probably won't be able to get to it till next week.
This is probably at the point where anything further should be sent to me privately.

Reversing one dimension of an array, in a generalized case
On the off chance that anyone is still interested, here is the corrected function using aperm():
z <- array(1:120,dim=2:5)
f2 <- function(a, wh) {
idx <- seq_len(length(dim(a)))
dims <- setdiff(idx, wh)
idx <- append(idx[-1], idx[1], wh-1)
aperm(apply(a, dims, rev), idx)
}
all.equal(f(z, 1), f2(z, 1))
# [1] TRUE
all.equal(f(z, 2), f2(z, 2))

Hi All:
I am just not understanding ggridges. The data I have are time series at different depths in the ocean. I want to make a joy plot of the time series by depth.
If I was just doing a ggplot2 line plot I would be doing:
ggplot(plotFrame, aes(x = time, y = cycle, group = depth)) + geom_line()
but translating that to ggridges has not worked right. Below is the result from dput() of a

what does the sum of square of Gaussian RVs with differen t variance obey?
This is a relatively recent article that is somewhat accessible.
Jensen, D. R., and Solomon, Herbert (1994), "Approximations to joint
distributions of definite quadratic forms", Journal of the American
Statistical Association, 89 , 480-486
It has references to previous work.
