  "Description": "Like similar profiling tools, the 'proffer' package\nautomatically detects sources of slowness in R code. The\ndistinguishing feature of 'proffer' is its utilization of\n'pprof', which supplies interactive visualizations that are\nefficient and easy to interpret. Behind the scenes, the\n'profile' package converts native Rprof() data to a protocol\nbuffer that 'pprof' understands. For the documentation of\n'proffer', visit <https://r-prof.github.io/proffer/>. To learn\nabout the implementations and methodologies of 'pprof',\n'profile', and protocol buffers, visit\n<https://github.com/google/pprof>. <https://protobuf.dev>, and\n<https://github.com/r-prof/profile>, respectively.",
