kandi X-RAY | ranger Summary

ranger is a C++ library typically used in Artificial Intelligence, Machine Learning applications. ranger has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

ranger is a fast implementation of random forests (Breiman 2001) or recursive partitioning, particularly suited for high dimensional data. Classification, regression, and survival forests are supported. Classification and regression forests are implemented as in the original Random Forest (Breiman 2001), survival forests as in Random Survival Forests (Ishwaran et al. 2008). Includes implementations of extremely randomized trees (Geurts et al. 2006) and quantile regression forests (Meinshausen 2006). ranger is written in C++, but a version for R is available, too. We recommend to use the R version. It is easy to install and use and the results are readily available for further analysis. The R version is as fast as the standalone C++ version.

            Mistake seems to be on the below line.

            1. You're running a for loop twice. Once is enough which will expose the object.

            2. You were accessing property like userData[j].cast, but userData is already an object so access it like userData.cast.

            I feel like there is probably a better way to do this in tidyverse than a for-loop. Start with a standard tibble/dataframe, and make a list where the name of the list elements are the unique values of one column (group_by?) and the list elements are all the values of another column.

            This seems to be some File system error more than maven issue, check if your disk has enough space to / you have the correct permissions to complete the build. Usually when I am building ranger this works for me the fastest and best.

            discord/js and angle of arc function
            Asked 2021-Dec-24 at 08:33

            Example:

            Try to get a handle on Arc and I'm running into a wall trying to figure out the end angle. I need something simple so can feed it a percentage and it make an arc that that's percent of a circle.

            I got the arc to start at the top and I know math.pi*2 will get me all the way around but when I try to modify that with the old *0.p trick of a converted percentage I get this.

            white is 0.1/10% red is 0.95/95% green is 0.5/50% blue is 0.7/70%

            but none of them look like that and I just can't figure out the way it's figuring the arc.

            Answered 2021-Dec-23 at 20:08

            It's because you forgot that you changed the starting angle. You need to make the angle, at which the arc ends, to be relative to the starting angle. So if you increase the value by the starting value it will work as expected:

            How to set ranger as default file manager
            Asked 2021-Dec-09 at 00:01

            Related: Here, Here, Here, & Here.

            I want to be able to use gui applications with ranger, e.g., I want to click a desktop folder icon & have it open in ranger.

            Steps I take & errors that follow:

            1. Set /home/ertecturing/.scripts/Ranger_Default_File_Manager.sh "%s" as default file manager in xfce settings
            2. Ranger_Default_File_Manager.sh runs xfce4-terminal -T "Ranger File Manager" -x ranger $@ This commands almost works, but it creates a directory error because directories given by $@ always start with only file:/// not file://// like they need to in order to function.
            3. I tried to add the missing 4th slash with this sed command someone shared with me: OUT=$(sed -e 's/\/\/\//\/\/\/\//g' $1) xfce4-terminal -T "Ranger File Manager" -x ranger $OUT I have little idea whether that first line's syntax is correct. The first line only produces blank output, but if I test a similar command echo $@ | sed "s/\/\/\//\/\/\/\//g" >> ~/Desktop/file it always outputs the 4th slash I'm looking for.

            Does anyone know a way to solve this issue? Help is highly appreciated.

            Changing your OUT variable to the command that you say works may be a better approach.

            Install ranger

            To install the ranger R package from CRAN, just run. R version >= 3.1 is required. With recent R versions, multithreading on Windows platforms should just work. If you compile yourself, the new RTools toolchain is required. To install the development version from GitHub using devtools, run. To install the C++ version of ranger in Linux or Mac OS X you will need a compiler supporting C++11 (i.e. gcc >= 4.7 or Clang >= 3.0) and Cmake. To build start a terminal from the ranger main directory and run the following commands. After compilation there should be an executable called "ranger" in the build directory. To run the C++ version in Microsoft Windows please cross compile or ask for a binary.
