Gas production from the North Sea is low because they imposed onerous windfall surtaxes on it so now it is unattractive to produce.

In R `nnls` (nonnegative least squares) does not guarantee integrality but in this case does give one solution and it happens to be integral: `library(nnls); nnls(A, b)`

The poorman package (on CRAN) implements a lot of tidyverse with no dependencies. Other packages that provide alternate implementations are datawizard and tidytable.

We used to call stuff like this "the warm body clause".

David P. Ellerman has a mathematical approach to accounting based on what he refers to as the Pacioli group. A provisional element of the Pacioli group looks like x//y where x and …

Of course it is possible to screw up but if you don't update your packages and record the date that does not seem to be R's fault.

The packages that were used in statistics were SAS, SPSS and Stata. perl is not a statistical package and has nowhere near the depth of statistical capabilities of R. Don't forget …

Is the subset R interpreter you wrote available on the net?

1. Before R commercial statistical packages were mainly used. You can, in principle, just use assembler too and develop everything yourself but it isn't practical. Regarding C/C++ …

What needs to be added is that before R the reproducibility problem in science was compounded by the fact that analyses were done with proprietary software limiting communication a…

Furthermore a test just twice as large would be sufficient to determine significance at the 1% level even with a two sided test if the same death rate continued to hold. ivm

The Mech Vent and ICU also used two sided tests.

Also they say they used the Fisher exact test and got a p value for mortality of 0.09 so it seems they were doing a two-sided test which is the default for fisher.test in R. ivm Ho…

Not being statistically significant is not a proof that it doesn't work -- it only means they could not reject the possibility that the results were due to chance. The possibility …

If we look at the secondary endpoints note that 3x as many died in the control group, 2.5x as many needed mechanical ventilation and one third more need to go to the ICU. Ivermecti…

The link refers to dplyr not being able to use databases but actually there is a database backend for it in package dbplyr. See https://dbplyr.tidyverse.org/

> plug a USB device in that has all my media files on it If you have multiple radios (like I do) that would require physically moving the USB from one to another.

The vroom R package is likely the fastest R package in read speed, not the ones used in this article. vroom was 13.1x faster than R's fread/data.table based on the read performance…

This may destroy viruses but it does not kill them as viruses are not alive.

Correct. One can write r"(c:\Windows\System32)" . Check out additional examples at the end of the help file: https://github.com/wch/r-source/blob/trunk/src/library/base/...
