Filling polygons with points
Dear list,
are there any possibilities to fill a polygon with a point pattern or with a symbol pattern like '+' oder '-' instead of shading lines?
Thanks in advance

Lightweight 'package' idea.
I'm often wanting to develop functions whilst manipulating data. But I
don't want to end up with a .RData full of functions and data. It
might be that I have functions that are re-usable but not worth
sticking in a package.
So I've tried to come up with a paradigm for function development
that more closely follows the way Matlab and Python do it (partly
inspired by a confused Matlab

How to improve the quality of curve/line plots?
Dear list,
I'm using the windows version of R. When plotting a curve or a line for time series with annual data , e. g. GDP growth 1991-2003, the line seems to exist of a lot of smaller lines. Printing the results the curves and lines seems to be "unclean" (because of using small resolution bitmaps?). Comparing the result of R with the same results of Excel the lines in excel seems

AW: How to improve the quality of curve/line plots?
Thanks for the tip using a smoothing technique before plotiing in order to get a curve instead of a line connecting the observations.
But that's not the solution for my main problem with the "unclean" line plot. In order to show my problem let's take this simple example:
> xval <- c(1, 2, 3, 4, 5, 6, 7, 8)
> yval <- c(10, 30, 40, 50, 70, 90, 100, 110)

Questions to RDCOMClient
Dear list members,
I'm using R in connection with the RDCOMClient and Excel. The more I use the
package, the more I'm fascinated of it. The possibilities of R can be
brought together with the necessities of outputing my socio-economical
research results in MS Office!
But I have some special questions concering the use of RDCOMClient and
perhaps you can help me solving them:

Creating Excel-Charts via RDCOMClient

density(x)
Dear experts,
when trying to estimate an kernel density function with density(x) I get the following
error message with imported data from either EXCEL or text files:
Error in density(spr) : argument must be numeric.
Other procedues such as truehist work. If I generate data within R density works fine.
Does anybody have an idea?

comparing row by row in matrix
I don't know the Russell-Rao coefficient but maybe this will help:
You can compute the number of times y and x are both 1 (that's what your
function f does) by counting 1s in y*x, i.e., sum(y*x), aka t(y)%*%x.
Ordinary matrix multiplication does this row-by-column, so if M and N are
two binary matrices, M%*%t(N) will have (i,j) entry equal to the count of 1s
in common to row i of M and

DBM databases for R?
Hello!
Can I use DBM databases (as they are used in Perl) for the import of

read.table() and scientific notation
Dear all,
I am having troubles importing values written as scientific notation
using read.table(). I'm sure this is a frequent problem, as many
people in my lab have this problem as well, so I'm sure that I just
have troubles googling for the right solution.
The problem is, that, given a file like that:
a 1 2e-4
b 2 3e-8

MacOS parallel::makeCluster fails
Hi all,
The call parallel::makeCluster(1L) hangs infinitely on my MacOS machine which seems to be already reported by some people (e.g., https://stat.ethz.ch/pipermail/r-devel/2018-February/075565.html).
However, the solutions posted on SO, GH or R-devel do not work in my case.
So far, I unsuccessfully tested ?
1. Couple of reboots
2. Adding 192.0.0.1 to /etc/hosts
3. Using R.app

Logit and Probit for Panel data
Dear R users/experts,
I've heard it's possible to estimate the above kinds of models in R. However, after (an admittedly brief) survey of the packages, I haven't found an obvious candidate. Can you offer any help? (Yes I'm a newby.)

[Hexagon] Type Legalization
Hi Craig,
protecting the transformation with:
if (TLI.isTypeLegal(VT)
&& TLI.isOperationLegal(ISD::SUB, VT)
&& TLI.isOperationLegal(ISD::ADD, VT)
&& TLI.isOperationLegal(ISD::SHL, VT)
&& TLI.isOperationLegal(ISD::SRA, VT)) {
shows the same result.

Looking for a sort of tapply() to data frames
Hi,
I read about the by() function, but it does not seem to do the job I
need. Here is the problem:
Say - I have a data frame, with three columns. The first one contains
strings that describe the data points, with repeats (for example, days
of a week). The other two contain numbers. Something like that:
Day val1 val2
Tue 1 2
Tue 2 8
Tue 3 5
Wed 1 2
Wed 1 8
etc.

MacOS parallel::makeCluster fails
Hi Thomas,
thanks for your reply (and thanks for your patience...).
I am now using the following minimal reprex:
> library(parallel)
> cl <- makeCluster(2L)
I freshly started the machine and did not open any other app. Just R.app (3.6.1).
After executing the second line of code, R seems to hang infinitely and does not respond.
The R process itself uses almost no CPU.

Status of llvm.experimental.vector.reduce.* intrinsics
I am currently working on a transformation pass that transforms
masked.load and masked.store intrinsics to (hopefully) increase
performance on targets where masked.load and masked.store are not legal.
To check if the loads and stores are necessary at all I take the mask
for the masked operations and want to reduce them to a single value.
vector.reduce.or seemed very handy to do the job.

[Hexagon] Type Legalization
Is VT a legal type on Hexagon? It looks like Hexagon may be setting SHL as
Custom for every defined vector type. Try adding TLI.isTypeLegal(VT) too.

slow loops in Monte Carlo Simulations
Hi there,
I am running Monte Carlo Simulations in R using ordinary "while
(condition)" loops. Since the number of iterations is something like
100.000 and within each iteration a given subsample is extended
sequentially it takes hours to run the simulation.
Does anyone know if there is either a way to avoid using loops in
Monte Carlo Simulations or how to include possible faster
