Excel Linen Driver

Read an Excel spreadsheet the same way as readxl, but slower. Assumes a well behaved table of data.

1 2	rexcel_readxl(path, sheet = 1L, col_names = TRUE, col_types = NULL, na = "", skip = 0)

`path`	Path to the xlsx file
`sheet`	Sheet name or an integer
`col_names`	TRUE (the default) indicating we should use the first row as column names, FALSE, indicating we should generate names (X1, X2, ..., Xn) or a character vector of names to apply.
`col_types`	Either NULL (the default) indicating we should guess the column types or a vector of column types (values must be "blank", "numeric", "date" or "text").
`na`	Values indicating missing values (if different from blank). Not yet used.
`skip`	Number of rows to skip.
