1 2	read_excel2(path, sheet = 1, col_names = TRUE, col_types = NULL, na = "", skip = 0, n_max = 1050000L)

`path`	Path to the xls/xlsx file
`sheet`	Sheet to read. Either a string (the name of a sheet), or an integer (the position of the sheet). Defaults to the first sheet.
`col_names`	Either `TRUE` to use the first row as column names, `FALSE` to number columns sequentially from `X1` to `Xn`, or a character vector giving a name for each column.
`col_types`	Either `NULL` to guess from the spreadsheet or a character vector containing "blank", "numeric", "date" or "text".
`na`	Missing value. By default readxl converts blank cells to missing data. Set this value if you have used a sentinel value for missing values.
`skip`	Number of rows to skip before reading any data.
`n_max`	Max number of rows to evalutate for internal function xls_col_types and xlsx_col_types. Defaults to all rows (1050000L)
