Get all the latest stock data with R language

This article uses the method mentioned here to improve, in order to obtain all the stock data in bulk, and the stock data is simple statistics.
The first use of the program requires a CSV file that records the names and codes of each stock.
The format is as follows:

As for the production, or quite simple, Baidu a stock code, or directly here, you can easily get all the stock code, and then put into Excel by the Space division, processing a bit can be. Here is a copy of my good, but only the Shanghai stock is interested can take to stockid.csv.
Note that if it is a different stock, please refer to the post I mentioned above to modify the code accordingly.

The SSE code is SS, deep Proof code is SZ, Hong Kong stock code is HK

such as Maotai: 6000519.SS, Vanke 000002.sz, Changjiang industrial 0001.hk

In the code, ‘.ss‘ change to something else.

library(quantmod)stock=read.csv(‘F:/Program Files/RStudio/stockid.csv‘,stringsAsFactors=F)data=list()forin1:length(stock$id)){  try(setSymbolLookup(TEMP=list(name=paste0(stock$id[i],‘.ss‘))))  try(getSymbols("TEMP",warnings=F))  try(data[stock$name[i]]<-list(TEMP))}

Data at this time is a list that stores all of the stock data in your CSV and can be used for example data$浦发银行 to get information about the stock.
Sample data:

Today is August 25, 2015, so the data obtained are the latest historical data.
You can see a total of 6 columns of data, each of which means:

• Open Price Open
• High prices
• Lowest price
• Close Price Close
• Volume volume
• Adjusted Price Adjust Prices

Here's a little bit of a look at the stock market and provide an example for everyone. The closing price of all stocks is extracted, and then the maximum minimum mean value of each stock closing price is calculated and so on.

library(plyr)closedata<-lapply(data,function(x){  x=as.data.frame(x)  return(list(x[,4])) #提取第4列，即收盘价})ldply(closedata,function(x)summary(x[[1]])) #对每个股票求summary

Partial Run Result:
