rstudio cache
Should cache storage be small?
In any case, cache storage should usually be small for internal use in the package (as opposed to the huge computation caching a package like targets supports). For further tooling around caching beside the memoise package and base R functions, refer to these packages (and their reverse dependencies!): storr by Rich FitzJohn.
What is the difference between a project template and a data cache?
The idea is the the data is dynamic and frequently updated. The ‘DataCache’ package sets a timer for the data and reads in the most recent version at set periods. The ‘ProjectTemplate’ package is far more than a caching system, rather, it is a data analysis project framework. The caching system is merely a part of it.
What is the primary function of r cache?
The primary function of ‘R.cache’ is evalWithMemoization (). It takes an expression to be evaluated, evaluates the expression, and stores both the created object, a in this case, and the expression itself.
Caching A Code Chunk in R Markdown
R Markdown has a built-in caching feature that can be enabled by settingcache=TRUEin the chunk’s header. The second time the chunk is run, both the visual output and any objectscreated are loaded from disk. If you are already using R Markdown foryour project or work, this is probably the only caching mechanism youwill need. R Markdown does have a m
‘Memoise’
The ‘memoise’ package brings in the function memoise(). When afunction is “memoised,” the inputs and outputs are remembered so that ifa function is passed the same inputs multiple times, the previouslycomputed output can be returned immediately, without re-evaluating thefunction call. This is an optimization technique from dynamicprogramming. The m
‘R.Cache’
The documentation for ‘R.cache’ is limited, but from what I can figureout, it implements memoisation while also linking to dependencies forcache invalidation. Further, and the main distinguishing feature betweenthis package and ‘memoise’, ‘R.cache’ memoises an expression, not justa function. The primary function of ‘R.cache’ is evalWithMemoization(
‘Mustashe’
I have recently described ‘mustashe’ in two previous posts (anintroduction to‘mustashe’and ‘mustashe’Explained), soI will keep the description here brief. The stash()function takes a name of the stashed value, an expressionto evaluate, and any dependencies. Just like ‘R.cache,’ if the value of the dependency xchanges, thenthe code is re-evaluated.
‘Datacache’
I won’t discuss the ‘DataCache’ package extensively because I personallyhave little use for it. It has already been explained by the author on aprevious R-Blogger’s post, ‘DataCaching’, so if you areinterested, I recommend reading that article. Also, it is not on CRANnor actively maintained on GitHub. In general it is intended toperiodically load d
‘Projecttemplate’
The ‘ProjectTemplate’ package is far more than a caching system,rather, it is a data analysis project framework. The caching system ismerely a part of it. However, the entire framework must be adopted inorder to use its caching system (there is a basic explanation of why in‘mustashe’ Explained - Why not use ’ProjectTemplate’s cache()function?).For
