H2o AutoML in R: XGBoost is not available; skipping it

Question

I'm trying to run H2o's automl and I want to see the results of XGboost in automl. When I'm trying to run this code:

aml1 <- h2o.automl(y = y, x = x, training_frame = train, keep_cross_validation_models = F, seed = 123)

I'm getting this message:

  |                            |   0% 16:25:37.796: AutoML: XGBoost is not available; skipping it. Job $03017f00000132d4ffffffff$_8c51b0759fd2e77fd8940b41f83340c2 was cancelled.

I'm using H2o 3.32.1.1 version on a Centos 7 linux server. I'm using R 3.6.0 version. I installed H2o using:

install.packages("h2o", type="source", repos=(c("http://h2o-release.s3.amazonaws.com/h2o/latest_stable_R"))) as given in: https://docs.h2o.ai/h2o/latest-stable/h2o-docs/downloading.html

Please help. I don't know why xgboost is not running in automl. And, how it could be fixed. I couldn't find any solution online yet to solve this issue.

EDIT

Issue got resolved by installing xgboost package in R. Thanks guys for your comments and directing me towards installing xgboost in R.
