Inconsistent behaviour when passing header and body arguments

[JSB97]

Same case, different issue. There seems to be inconsistent behaviour when trying to pass both header and body arguments. Using both fails to return the 1st column and all headers. Just using body works, but it would ideal to just pass the header argument as one will not always know in advance what row to parse data from.

When passing both the header and body xpaths

u4 <- "/SomePath/6501.Yuho.pdf_table_30.html" t4 <- htmltab(doc = u4,header="/html/body/table/thead",body = "//tr[position() > 2]") Warning messages: 1: Argument 'which' left unspecified. Choosing first table. 2: No header generated. Try passing information to header or colNames. Header XPath was /html/body/table/thead

head(t4) V2 V3 V4 V5 V6 V7 V8 1 86,975 70,265 32,050 (1,686) 16,751 3,951 209,992 76,534 2 24,701 14,795 84,814 (8,468) 7,419 14,105 145,834 10,164 3 97,340 58,002 30,259 (3,739) 9,512 8,274 203,387 48,779 4 62,131 35,556 41,975 (2,093) 597 2,673 142,932 24,617 5 95,331 122,966 59,537 (9,497) 3,137 14,586 295,557 19,570 6 132,260 173,340 93,394 (13,288) 2,437 17,860 419,291 43,059

When passing just the body; correct output is returned.
