SAS Macro Variable in R
...new to R and would like to implement a SAS-like macro variable
in R.
What I'd like to do is take the simple R code below and change the
"=TEF" to different letters to refer to different companies' data for
download.
# DOWNLOADS FILES FROM YAHOO INTERNET
download.file('http://ichart.yahoo.com/table.csv?s=TEF.MC&a=00&b=1&c=2003&d=05&e=23&f=2009&g=d&ignore=.csv',
'c:\\projects\\stock data\\data\\test.csv',quiet=TRUE)
As you can see the text I want to change is within the quoted Internet
address. Is this possible in R?
Thanks in adv...

read.table behavior for Dates.
...ad.table imports a table that includes a header called 'Date', it
tries to recognize the date format. For example, if one imports this data
from Yahoo finance, the Date column is automatically transformed to Y-m-d,
whereis in the data it appears as m/d/Y:
myData <-
read.csv("http://ichart.finance.yahoo.com/table.csv?s=GOOG&a=07&b=19&c=2004&d=03&e=16&f=2010&g=d&ignore=.csv")
However, it does not actually convert the variable to Date format.
MyData$Date is still a factor. This combination of converting the format but
not attributing the 'Date&...

plotting moving range control chart
...Analyst" (v. 0.6.0) provides an option to produce a moving
range chart with individuals data. The example given in the qAnalyst manual
for function spc yields an individuals chart:

testType=1,
> data(rawWeight)
> ichart=spc(x=rawWeight$rawWeight, sg=2, type="i", name="weight",

> mrchart = spc(x = rawWeight$rawWeight, sg = 2, type = "mr&...

MLDownloader 7.1 fails to download data from yahoo
...esult of
grep Canonicalize MLD.txt
The www.trading-tools.com GETs appear to work. Because these retrieve the data to update the stock symbol lists. They are also repeatable with wget.
But notice the embedded \n in the GETs from Yahoo. wget doesn't like them unless the \n are removed.
