Been trying to construct a list of tickers to feed into the priceIts
function and yes I could just use the c("ticker1", "ticker2") input
manually in the download function to gather a group but would prefer to
set it up as a list to draw from so I can manipulate the list whenever I
want.
using paste() in a number of ways, i can add the comma to the ticker but
it always occurs inside the quotes separating each ticker (either before
or after the ticker depending on how i set it up) while I am looking to
separate each ticker in the vector...
getting this...
# tickerlist.one is matrix of tickers in character format...
1 2 3 4 5 6 7 8 9 10
"AIG" "C" "CSCO" "FDX" "GE" "GM" "IBM" "INTC" "IP" "JNJ"
#
tickerlist.one<-paste(tickerlist.one, sep=",")
[1] "AIG," "C," "CSCO," "FDX," "GE," "GM," "IBM," "INTC,"
"IP,"
[10] "JNJ," "KO," "MER," "MMM," "MSFT," "PFE," "WMT," "XOM,"
when, of course, i want
"AIG", "C", "CSCO"...
tried a number of different methods & functions, even creating a matrix
of commas and trying to mesh the two sets together using matrix
addition. Don't laugh...
Anyway, i humbly offer a function that i found while searching in the
hopes someone can drop a line of code to push my project forward-
formatC() which can do a number of things including formatting how much
space can be allocated to either side of the data point...Of course, the
formatting is a bit rough since I "pushed" the data to one side or the
other of the quotes...anyway, I thought it was an unusual way to
manipulate text.
I.E.-
ticker.list1[,1:10]
1 2 3 4 5 6 7 8 9 10
"AIG" "C" "CSCO" "FDX" "GE" "GM" "IBM" "INTC" "IP" "JNJ"
> formatC(ticker.list1[,1:10], wid=5)
1 2 3 4 5 6 7 8 9
10
" AIG" " C" " CSCO" " FDX" " GE" " GM" " IBM" " INTC" " IP"
" JNJ"
> formatC(ticker.list1[,1:10], wid=-5)
1 2 3 4 5 6 7 8 9
10
"AIG " "C " "CSCO " "FDX " "GE " "GM " "IBM " "INTC " "IP "
"JNJ "

Thanks for your time.
