Hi Ravi,

While performing partition function in regression I'm getting below error
"Error in all$Sale_Price : $ operator is invalid for atomic vectors"

PFB the codes too for your reference:

partition <- createDataPartition(y=all$Sale_Price,p=.5,
list=FALSE)
 
I need some advice regarding the use of R in text analytics/ data mining.. Please help me with this. I want tio use R to pull data from websites and then use NLP. Any suitable publication will be appreciated
