Examples

# NOT RUN {
# data.frame object
# data(iris)


## EXAMPLE 1 : SET default local repository using aoptions() function.

# creating example repository
exampleRepoDir <- tempfile()
createLocalRepo(exampleRepoDir)

# "repodDir" parameter in each archivist function will be default and set to exampleRepoDir.
aoptions(key = "repoDir", value = exampleRepoDir)

data(iris)
data(swiss)
# From this moment repoDir parameter may be ommitted in the following functions
saveToLocalRepo(iris)
saveToLocalRepo(swiss)
showLocalRepo()
showLocalRepo(method = "tags")
zipLocalRepo()
file.remove(file.path(getwd(), "repository.zip"))
iris2 <- loadFromLocalRepo( "ff575c2" , value = TRUE)
searchInLocalRepo("name:i", fixed = F)
getTagsLocal("ff575c261c949d073b2895b05d1097c3")
rmFromLocalRepo("4c43f")
showLocalRepo()
summaryLocalRepo()

# REMEMBER that in deleteRepo you MUST specify repoDir parameter!
# deleteLocalRepo doesn't take setLocalRepo's settings into consideration
deleteLocalRepo( exampleRepoDir, deleteRoot = TRUE)
rm( exampleRepoDir )

## EXAMPLE 2 : SET default Github repository using aoptions() function.
aoptions(key = "user", value = "pbiecek")
aoptions(key = "repo", value = "archivist")

# From this moment user and repo parameters may be ommitted in the following functions:
showRemoteRepo()
loadFromRemoteRepo( "ff575c261c949d073b2895b05d1097c3")
this <- loadFromRemoteRepo( "ff", value = T)
file.remove(file.path(getwd(), "repository.zip")) # We can remove this zip file
searchInRemoteRepo( "name:", fixed= FALSE)
getTagsGithub("ff575c261c949d073b2895b05d1097c3")
summaryRemoteRepo( )
searchInRemoteRepo( pattern=c("varname:Sepal.Width", "class:lm", "name:myplot123"),
                         intersect = FALSE )
## EXAMPLE 3 : SET default Github repository using aoptions() function.
showRemoteRepo('Museum', 'MarcinKosinski', subdir = 'ex1')
aoptions('repo', 'Museum')
aoptions('user', 'MarcinKosinski')
aoptions('subdir', 'ex1')
aoptions('branch', 'master')
showRemoteRepo()
showRemoteRepo(subdir = 'ex2')

aoptions('subdir')

## EXAMPLE 4 : SET sha256 as a hasing algorithm
aoptions("hashFunction", value = "sha256")
exampleRepoDir <- tempfile()
createLocalRepo(exampleRepoDir)
aoptions(key = "repoDir", value = exampleRepoDir)

data(iris)
saveToLocalRepo(iris)
getTagsLocal(digest::digest(iris, algo = "sha256"))

# }
