Hi-
I would like to be able to change the value of SymA below and download a file
from the corresponding URL. Hardcoded, this line works fine:
Symbol<-
read.csv("http://ichart.finance.yahoo.com/table.csv?s=SPY&ignore=.csv";,
stringsAsFactors=F)
However, when I incorporate using a variable for the ticker, it no longer
works.
SymA<- "SPY"
Sym1<-
cat('http://ichart.finance.yahoo.com/table.csv?s=",SymA,"&ignore=.csv",sep="";;)
Symbol<- read.csv(Sym1, stringsAsFactors=F)
I know that the problem lies in the concatenation, but I've tried different
variations of cat() and toString() (and others) with SymA and Sym1 but cannot
seem to get a string together that will work. Would appreciate any suggestions
for this simple problem??
Thank you.
