R 包 readHTMLTable 中的抓取错误：make.names 中的错误无效多字节字符串

Question

I am trying to get some data from a HTML web by using readHTMLTable.

The web contains some Chinese utf-8 code, so it usually gives me some error.

First try:

u = "http://app.finance.ifeng.com/hq/stock_daily.php?code=sh600030"
url = htmlParse(u)
tbls = readHTMLTable(u,asText= TRUE)

dat <- data.frame(tbls)

ERROR:Error in make.names(vnames, unique = TRUE) : invalid multibyte string 5

Answer 1

The solution is to add the argument encoding = "UTF-8" , in my case, to these functions or connections. More generally, providing the default encoding or a hook before parsing might be a more robust solution.

url = htmlParse(baseURL, encoding="GB2312") table=readHTMLTable(url,header=,which=1,encoding="UTF-8")
