R SDK for Arvados

Examples of usage:

--------------------------------------------------------------------------------------------------------------------------------

#Initialize API:

arv <- Arvados$new("insert_token", "insert_host_name")

--------------------------------------------------------------------------------------------------------------------------------

#Get collection:

arv$getCollection("uuid")

--------------------------------------------------------------------------------------------------------------------------------

#List collections:

collectionList <- arv$listCollections(list("uuid", "=" "aaaaa-bbbbb-ccccccccccccccc"), limit = 10, offset = 2)

--------------------------------------------------------------------------------------------------------------------------------

#Delete collection:

deletedCollection <- arv$deleteCollection("uuid")

--------------------------------------------------------------------------------------------------------------------------------

#Update collection:

updatedCollection <- arv$updateCollection("uuid", list(collection = list(name = "new_name", description = "new_desciption")))

--------------------------------------------------------------------------------------------------------------------------------

#Create collection:

updatedCollection <- arv$createCollection("uuid", list(collection = list(name = "new_name", description = "new_desciption")))

--------------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------------

#Collection manipulation:

--------------------------------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------------------------------------------------------------------

#Create collection object:

arv <- Arvados$new("insert_token", "insert_host_name")
collection <- Collection$new(arv, "uuid")

--------------------------------------------------------------------------------------------------------------------------------

#Print content of the collection (directory/folder tree structure)

collection$printFileContent()

--------------------------------------------------------------------------------------------------------------------------------

#Get file/folder content as character vector

collection$getFileContent()

--------------------------------------------------------------------------------------------------------------------------------

#This will return ArvadosFile or Subcollection from internal tree-like structure.

arvadosFile <- collection$get("location/to/my/file.cpp")

#or

arvadosSubcollection <- collection$get("location/to/my/directory/")

--------------------------------------------------------------------------------------------------------------------------------

#Read whole file or just a portion of it.

fileContent <- arvadosFile$read(offset = 1024, length = 512)

--------------------------------------------------------------------------------------------------------------------------------

#Get ArvadosFile or Subcollection size 

size <- arvadosFile$getSizeInBytes()
size <- arvadosSubcollection$getSizeInBytes()

--------------------------------------------------------------------------------------------------------------------------------

#Create new file in a collection

#Call structure

collection$createNewFile("relativePath", "fileContent", "fileContentType")

#Example

collection$createNewFile("cpp/src/main.cpp", "#include<iostream>", "text/html")

--------------------------------------------------------------------------------------------------------------------------------

#Write to existing file (Override current content of the file)

arvadosFile <- collection$get("location/to/my/file.cpp")

arvadosFile$write("This is new file content")

--------------------------------------------------------------------------------------------------------------------------------
