Up front, "1,3,4" != 1. It seems you should look to split the strings using strsplit(., ",").

One approach is to define a helper function that matches for a specific animal, then bind the columns to the original frame.

Note that some wrangling is done to get rid of whitespace to identify the unique animals to query.

We can use stri_replace_all_regex to replace your color_1 into integers together with the arithmetic operator.

Here I've stored your values into a vector color_1_convert. We can use this as the input in stri_replace_all_regex for better management of the values.

How to make a rank column in R

Asked 2022-Mar-07 at 16:19

I have a database with columns M1, M2 and M3. These M values correspond to the values obtained by each method. My idea is now to make a rank column for each of them. For M1 and M2, the rank will be from the highest value to the lowest value and M3 in reverse. I made the output table for you to see.

With your show samples, attempts; please try following awk code. Since you are opening files all together it may fail with infamous "too many files opened error" So to avoid that have all values into an array and in END block of this awk code print them one by one and I am closing them ASAP all contents are getting printed to output file.

Break Apart a String into Separate Columns R

Asked 2021-Dec-17 at 20:39

I am trying to tidy up some data that is all contained in 1 column called "game_info" as a string. This data contains college basketball upcoming game data, with the Date, Time, Team IDs, Team Names, etc. Ideally each one of those would be their own column. I have tried separating with a space delimiter, but that has not worked well since there are teams such as "Duke" with 1 part to their name, and teams with 2 to 3 parts to their name (Michigan State, South Dakota State, etc). There also teams with "-" dashes in their name.

Install pykokkos-base

You can install this package via CMake or Python's setup.py. The important cmake options are:. By default, CMake will enable the layouts and memory traits options if the Kokkos installation was not built with CUDA support. If Kokkos was built with CUDA support, these options will be disabled by default due to unreasonable compilation times (> 1 hour). The ENABLE_VIEW_RANKS option (defaults to a value of 4) is the max number of ranks for Kokkos::View<...> that can be returned to Python. For example, value of 4 means that views of data type T*, T**, T***, and T**** can be returned to python but T***** and higher cannot. Increasing this value up to 7 can dramatically increase the length of time required to compile the bindings.
ENABLE_VIEW_RANKS (integer)
ENABLE_LAYOUTS (bool)
ENABLE_MEMORY_TRAITS (bool)
ENABLE_INTERNAL_KOKKOS (bool)
If the ENABLE_INTERNAL_KOKKOS option is not specified the first time CMake is run, CMake will try to find an existing Kokkos installation. If no existing installation is found, it will build and install Kokkos from a submodule. When Kokkos is added as a submodule, you can configure the submodule as you would normally configure Kokkos. However, due to some general awkwardness configuring cmake from setup.py (especially via pip install), CMake tries to "automatically" configure reasonable default CMake settings for the Kokkos submodule.
Does external/kokkos/CMakeLists.txt exists? YES: assumes the submodule is already checked out If compute node does not have internet access, checkout submodule before installing! NO: does .gitmodules exist? YES: git submodule update --init external/kokkos NO: git clone -b master https://github.com/kokkos/kokkos.git external/kokkos
Set BUILD_SHARED_LIBS=ON
Set Kokkos_ENABLE_SERIAL=ON
find_package(OpenMP) Was OpenMP found? YES: set Kokkos_ENABLE_OPENMP=ON NO: find_package(Threads) Was Threads found? YES: set Kokkos_ENABLE_PTHREADS=ON (if not Windows)
find_package(CUDA) Was CUDA found? YES: set: Kokkos_ENABLE_CUDA=ON Kokkos_ENABLE_CUDA_UVM=ON Kokkos_ENABLE_CUDA_LAMBDA=ON Kokkos_ENABLE_CUDA_CONSTEXPR=ON
