包R Azure机器学习

Question

I'm new in Azure and I would like to run my R Code, I read how it's work but I have problem to run my packages but I always get errors like this .

package 'ParamHelpers' required by 'mlr' could not be found

And when I run in Rstudio i don't have the same errors

I have a zip file with inside the zip packages

install.packages("src/Metrics_0.1.1.zip", lib = ".", repos = NULL, verbose = TRUE)
install.packages("src/checkmate_1.7.0.zip", lib = ".", repos = NULL, verbose = TRUE)
install.packages("src/mlr_2.7.zip", lib = ".", repos = NULL, verbose = TRUE)
install.packages("src/xgboost_0.4-2.zip", lib = ".", repos = NULL, verbose = TRUE)
install.packages("src/BBmisc_1.9.zip", lib = ".", repos = NULL, verbose = TRUE)

library(xgboost)
library(Metrics, lib.loc=".", verbose=TRUE)
library(checkmate, lib.loc=".", verbose=TRUE)
library(BBmisc, lib.loc=".", verbose=TRUE)
library(mlr, lib.loc=".", verbose=TRUE)
library(Hmisc)
packageVersion("mlr")

You need to add all the packages to your zip-file that mlr needs. Both BBmisc and ParamHelpers are not available on Azure, so you need to add these to the zip-file containing the other packages like mlr.

Here is a list of available packages in Azure ML .

and here is the overview of packages mlr depends on and suggests
