[R] accessing members of a list

[Rui Barradas]

Hello,

Maybe the following will help.



library(XML)
oneurl="http://www.tutiempo.net/en/Climate/FUKUSHIMA/11-2012/475950.htm"
temp.tables=readHTMLTable(oneurl, which = 3)

str(temp.tables)

temp.tables <- temp.tables[-31,]
temp.tables[,1:10] <- lapply(temp.tables[,1:10], function(x) 
as.numeric(as.character(x)))

str(temp.tables)


Hope this helps,

Rui Barradas
