kandi X-RAY | REngine Summary

REngine is a Java library typically used in Artificial Intelligence, Machine Learning applications. REngine has no bugs, it has no vulnerabilities, it has build file available and it has low support. However REngine has a Non-SPDX License. You can download it from GitHub, Maven.

REngine is a general Java interface to R supporting multiple back-ends such as JRI and Rserve. It allows Java code to evaluate R expressions, push and pull data. Since it is backend-agnostic, the same code can be used to embed R into a Java process or use a cluster of R servers to perform statisical computations. The sources can be compiled simply by using. Maven is also supported (including unit tests) and can be run using make mvn.pkg. If you want to run mvn by hamd you can do so, but note that the Maven project requires a different directory structure which can be created by calling mkmvn.sh (unix only as it uses symlinks).

JRI is currently not supported on Big Sur, because Apple has removed the last traces of Java support - here the JavaVM framework, so you have two options:

use --disable-jri when installing rJava from sources (e.g. via install.packages("rJava", configure.args="--disable-jri"))
use rJava from CRAN (i.e., install the binary version of rJava - not source)

The issue tracking this is #248

You most likely invoke R the wrong way. Use /usr/bin/R which is a frontend which sets R_HOME for further use by the other components.

CreateDataFrame() wants an array of IEnumerable, but a1 is an array of seq, which is F#'s way of saying IEnumerable; you just need another cast in there. This compiles for me (though I haven't actually run it):

Here are your issues:

/usr/bin/ld: cannot find -lpcre2-8 /usr/bin/ld: cannot find -lbz2

The linker (ld) cant find these libraries. I had a similar issue with just lpcre2-8 on Ubuntu. I fixed my issue by installing:

sudo apt-get libpcre2-dev

I imagine the second error with bz2 will be fixed with:

sudo apt-get libbz2-dev

Hope That helps

ANSWER

Answered 2020-Jan-20 at 02:50

This might work and could be better with a more refined regex. My columns might be off from the copy/paste process but the logic should be correct

Get the units

df['Unit'] = df['Unit'].str.split('(.+?(?=\d{5}))')

Get the lengths

lengths = df['AM/PM'].str.split(r'\\r').explode()

Explode the Units, remove the empty entries from the regex and concat the lengths back to the dataframe

df = pd.concat([df.explode('Unit').query("Unit != ''"), lengths], axis=1)
