The current implementation of the [radixsort builtin](https://github.com/oracle/fastr/blob/master/com.oracle.truffle.r.nodes.builtin/src/com/oracle/truffle/r/nodes/builtin/base/SortFunctions.java#L276) delegates to shellsort (order builtin), but it should instead implement the [same algorithm](https://github.com/wch/r-source/blob/trunk/src/main/radixsort.c#L1545) as the reference implementation. The implementation can be tested on...

Run `dplyr` package examples

11

Make sure FastR can install `dplyr` and run `dplyr` examples. Some issues: `dplyr` uses `Rcpp`, which under some circumstances (e.g. in function `duplicated`) invokes `DATAPTR` macro on character vector, which...

Implement the `adist` builtin

2

From the documentation: Compute the approximate string distance between character vectors. The distance is a generalized Levenshtein (edit) distance, giving the minimal possibly weighted number of insertions, deletions and substitutions...

From the documentation: Return the names of all the built-in objects. These are fetched directly from the symbol table of the R interpreter. In FastR the list of builtins is...

Example: `.Internal(address(c(1,2,3)))`. In FastR case we can return the hash-code of the Java object.

I'm always frustrated when I need to switch tabs when I want to run OQL query on one heap dump and want to compare its result on another heap dump,...

Provide history of executed OQL queries

1

I'm always frustrated when I forget to save my OQL queries. I think that execution history similar to what SQL tools have would be great feature: https://docs.devart.com/studio-for-mysql/writing-and-executing-sql-statements/query-execution-history.html. I would prefer...

Consider not using R API in the forked child

1

The function `C_execute` forks the current process and in the child process it uses some R API ([example](https://github.com/jeroen/sys/blob/master/src/exec.c#L177)). The potential issue with that is that, e.g., with the `ALTREP` framework...
