Error message when installing TesorFlow for RStudio

[Snehal_Patel]

I am attempting to install TensorFlow for R using precisely the instructions provided at :
https://tensorflow.rstudio.com/installation/#installation:

Installation

First, install the tensorflow R package from GitHub as follows:

install.packages("tensorflow")

Then, use the install_tensorflow() function to install TensorFlow. Note that on Windows you need a working installation of Anaconda.

library(tensorflow)
install_tensorflow()

You can confirm that the installation succeeded with:

library(tensorflow)
tf$constant("Hellow Tensorflow")

## tf.Tensor(b'Hellow Tensorflow', shape=(), dtype=string)

This will provide you with a default installation of TensorFlow suitable for use with the tensorflow R package

The output in RStudio is below:

> install.packages("tensorflow")
