dataframe - Assistance Required to append to existing R Data Frame Object -

i trying pull historical price information asx200 list of companies. issue have r data frame using keeps getting overwritten (instead of appended to). final dataframe contains data last asx200 ticker. pls see attempt below:

library(xml)  url <- "http://www.asx200list.com" getasx200 <- readhtmltable(url, which=1, header = true) codes <- getasx200$code codes <- lapply(codes, as.character)  (i in 1:200) {   url2 <- paste("http://ichart.finance.yahoo.com/table.csv?s=", codes[i], ".ax", sep = "")   dat <- read.csv(url2)   dat$date <- as.date(dat$date, "%y-%m-%d")   dat$code <- codes[i] } 

collecting list little bit tricky. here's example:

library(xml)  url <- "http://www.asx200list.com" getasx200 <- readhtmltable(url, which=1, header = true) codes <- getasx200$code codes <- lapply(codes, as.character)   datlist <- list()  (i in 1:200) {   url2 <- paste("http://ichart.finance.yahoo.com/table.csv?s=", codes[i], ".ax", sep = "")   dat <- read.csv(url2)   dat$date <- as.date(dat$date, "%y-%m-%d")   dat$code <- codes[i]    datlist <- c(datlist, list(dat)) }  print(head(datlist[[1]]))
