In rstudio/profvis: Interactive Visualizations for Profiling R Code

profvis 0.3.8

• print() gains an aggregate argument. Use print(profvis(f()), aggregate = TRUE) to aggregate frames by name in the flamegraph. This makes it easier to see the big picture (#115). Set the profvis.aggregate global option to TRUE to change the default.

• For C function declarations that take no parameters, added void parameter.

profvis 0.3.7

• Resolved #102:" Added simplify argument. When TRUE (the default), the profiles are simplified using the new filter.callframes argument of R 4.0. This argument has no effect on older R versions. (#118)

• Fixed #111: auto-scrolling to lines of code did not work in some browsers. (#113)

profvis 0.3.6

• Added a profvis Shiny module, for starting/stopping the profiler during the execution of a Shiny application. This can be helpful if you don't want to profile the entire execution of an app, only a certain operation. To install the profvis module into your app, add profvis_ui("profvis") to your UI, and callModule(profvis_server, "profvis") to your server function.

• Exported parse_rprof function.

profvis 0.3.5

• Fixed problem with development build of R where source refs are turned on by default (reported by Tomas Kalibera).

profvis 0.3.4

• Fixed #77: The contents of <expr> are now always listed first.

• Addressed #85: The pause() function is now implemented in C, which reduces the amount of data generated.

• Fixed #86: In the data pane, toggling between horizontal/vertical view caused the flame graph to render on top of the tree view.

• Fixed #84: In the data pane, leaf nodes (representing top-most calls on the stack) were not displayed.

• Addressed #82: In the data pane, if a node has exactly one child, that child will automatically be expanded. This makes it more efficient to explore the data. (#83)

• Fixed #50: In the data pane, function calls were shown in reverse order.

profvis 0.3.3

• Fixed #68: Profvis threw an error when a package was installed using devtools::install_github(args = "--with-keep.source").

• Fix bug where, when loading a profile that didn't contain memory data, profvis would throw an error. #66

• Fixed #73: Profvis would throw an error if used on code sourced from a remote URL.
