Hi,
This works:
dataspy['20121003/20121009']
?# ? ? ? ? ?SPY.Open SPY.High SPY.Low SPY.Close SPY.Volume SPY.Adjusted
#2012-10-03 ? 144.89 ? 145.43 ?144.13 ? ?145.09 ?121283100 ? ? ? 145.09
#2012-10-04 ? 145.64 ? 146.34 ?145.44 ? ?146.13 ?124311600 ? ? ? 146.13
#2012-10-05 ? 146.91 ? 147.16 ?145.70 ? ?146.14 ?124842100 ? ? ? 146.14
#2012-10-08 ? 145.60 ? 146.12 ?145.31 ? ?145.64 ? 78415400 ? ? ? 145.64
#2012-10-09 ? 145.53 ? 145.65 ?144.15 ? ?144.20 ?148872900 ? ? ? 144.20
This also works:
startDate<-"2012-10-03"
?endDate<-"2012-10-08"
?startEndDate<-paste(startDate,endDate,sep="::")
?dataspy[startEndDate,]
# ? ? ? ? ? SPY.Open SPY.High SPY.Low SPY.Close SPY.Volume SPY.Adjusted
#2012-10-03 ? 144.89 ? 145.43 ?144.13 ? ?145.09 ?121283100 ? ? ? 145.09
#2012-10-04 ? 145.64 ? 146.34 ?145.44 ? ?146.13 ?124311600 ? ? ? 146.13
#2012-10-05 ? 146.91 ? 147.16 ?145.70 ? ?146.14 ?124842100 ? ? ? 146.14
#2012-10-08 ? 145.60 ? 146.12 ?145.31 ? ?145.64 ? 78415400 ? ? ? 145.64

Subject: Re: [R] Date format conversion from "2012-09-20" to "2012:09:20"
Hi R,
How to get the range of values form startDate to lastDate as given below?.
#*****************************************************************
# Load historical data
#******************************************************************
library('quantmod')
endDate =Sys.Date()
startDate = as.Date(endDate-30, order="ymd")
dataspy = getSymbols("SPY", from = startDate, to=endDate, auto.assign =
FALSE)
lastDate=startDate+5
#subset first 5 days
dataspy['startDate::lastDate']
print(dataspy)
Thanks
veepsirtt
