Hi A.K

-----------------------------
library(XML)
URL <-  "
http://money.securebank.in/index.php?option=com_dashboard&view=history&Itemid=56&startdate=01/01/2013&enddate=6/9/2014&exchange=MCX&sid=1"

doc <- htmlParse(URL)
tableNodes <- getNodeSet(doc, "//table")
dat1 <- readHTMLTable(tableNodes[[4]], colClasses=c("numeric","character",
"character", "numeric", "character", "numeric", "numeric", "character",
"numeric"),stringsAsFactors=FALSE)
dat1$DATE <- as.Date(dat1$DATE, "%d-%m-%Y")
str(dat1)
------------------------------


I got this error,while running the above code under RStudio.,
how to correct it?.

> dat1 <- readHTMLTable(tableNodes[[4]],
colClasses=c("numeric","character", "character", "numeric", "character",
"numeric", "numeric", "character", " ..." ... [TRUNCATED]
Error in readHTMLTable(tableNodes[[4]], colClasses = c("numeric",
"character",  :
  error in evaluating the argument 'doc' in selecting a method for function
'readHTMLTable': Error in tableNodes[[4]] : subscript out of bounds
