download.file - it works on my Mac but not on Windows.
Hi:
I am working with someone remotely to allow them access to our data.
The follow command using "download.file" works perfectly on my Mac:

We are having some very strange problems with R on WIndows, both with

[OT]Web-Based Data Brushing
I apologize for the off-topic post, but my Google search did not turn
up much and I thought people on this list my have knowledge of this.
I am looking for examples of data brushing (i.e. dynmaic linked
plots) either on a web site, or in a web-based application, such as
an AJAX app. Even better if there is a way to do this in R.
Thanks for any help.

Adding OPeNDAP to the ncdf package on windows
Hi:
Russ Moffit of our Honolulu Lab has made a modification to the R
netcdf package 'ncdf' so that it can access remote netcdf files
using OPenDAP (http://www.opendap.org). The package works on Linux,
and with help from Don MacQueen was also ported to Macintosh OS X.
We have had a lot of demand for this to be ported to Windows also,
but it is beyond our capabilities. If there is

StructTS
I apologize in advance if I picked the wrong list to post this to. I
have made an effort to find the answers to these questions on CRAN,
but if they are there, I couldn't find them, and I was going to email
the developer of StructTS directly but could not find who that is.
I have 2 interrelated questions about StructTS

R for Windows 32-bit mode versus 64-bit mode
Hi All:
We are developing (actually updating) a piece of code that runs in R. Due to some limitations of some the libraries we use, at the present time we would be limited to the 32-bit version of R on Windows. Does anyone have a feel (or even real knowledge) if most people these days run R on Windows in 32-bit or 64-bit mode? This would affect some development decisions.
Thanks

How to create following chart for visualizing multivariate time series
Let me take an artifical matrix :
dat = matrix(rnorm(200*200), 200, 200)
My goal is to visualize this matrix according to the procedure, described in previous mails. I took Mendelssohn's advice and got following advice :
?plot.im
Z <- setcov(owin())
plot(Z) .................... etc
However I can not reproduce this example in my problem. How I can change my data

Fwd: Re: How to create following chart for visualizing multivariate time series
Thanks David, It is working. Holtman's also gave me a solution but, I wanted to have a color pallet for description of colors, that was not in his solution.
However I need one small modification. If I want to plot only lower diagonal elements of 'dat' then how should I proceed? What I want is, to visualize only lower diagonal elements and having the color pallet on them only. Also

httr::content without message
Thanks to all that replied. I had just looked through the httr code and sure enough for a .csv mime time it calls readr::read_csv(). The httr::content docs suggest not using automatic parsing in a package, rather to determine mime type and parse yourself and Ben's suggestion also works if I do:
junk <- readr::read_csv(r1$content, col_types = cols())
Perfect. Using httr rather than

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.

Calculating Portfolio Standard deviation
Dear R helpers
I have following data

prices_df <- data.frame(ABC = c(17,24,15,22,16,22,17,22,15,19),
DEF = c(22,28,20,20,28,26,29,18,24,21),

Questions about EM algorithm
Dear all:
Assume I have 3 distributions, x1, x2, and x3.
x1 ~ normal(mu1, sd1)
x2 ~ normal(mu2, sd2)
x3 ~ normal(mu3, sd3)
y1 = x1 + x2
y2 = x1 + x3
Now that the data I can observed is only y1 and y2. It is
easy to estimate (mu1+m2), (mu1+mu3), (sd1^2+sd2^2) and
(sd1^2+sd3^2) by EM algorithm since
y1 ~ normal(mu1+mu2, sqrt(sd1^2+sd2^2)) and
y2 ~ normal(mu1+mu3, sqrt(sd1^2+sd3^2))
However, I want

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.

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

httr::content without message
Ahoy!
That's a message generated by the readr::read_table() function (or it's friends). You can suppress it a number of ways, but this should work as httr::content() will pass through arguments, like col_types = cols(), to the file reader.
junk <- httr::content(r1, col_types = cols())

Reversing one dimension of an array, in a generalized case
Thanks to all for responses/. There was a question of exactly what was wanted. It is the generalization of the obvious example I gave,
>>> junk1 <- junk[, rev(seq_len(10), ]
so that
junk[1,1,1 ] = junk1[1,10,1]
junk[1,2,1] = junk1[1,9,1]
etc.
The genesis of this is the program is downloading data from a variety of sources on (time, altitude, lat, lon) coordinates, but all

RMarkdown question
Although it is not an elegant solution, but if your output format is
HTML, you can add an arbitrary empty HTML element like <span
id="foo"></span> before your code chunk. Then you can jump to this
<span> via a link like "see [this code chunk](#foo)".
