Unable to save as a dataframe and not getting headers in a csv

[NJStudent1]

Hi,

I have two questions on the package's execution.

1. The document description says, “Data can be returned as a data frame or written to a file (see ‘output_file‘ parameter).” However, I am getting the following error when I try to retrieve the data as a dataframe.

df2018w1 <- get_bulk_patent_data(year = 2018, week = 1)

Error in cat("WKU,Title,App_Date,Issue_Date,Inventor,Assignee,ICL_Class,References,Claims\n",  : 
  argument "output_file" is missing, with no default

2. The code runs fine if I write the data to a csv but there are no column names in the csv output. Please tell how to get them.

Thanks!
