Hi all,

 

I have a file with a dozen weather stations with a dozen weather
variables.  I am trying to get a percentile of each variable for each
station.  I imported the file into a data frame Data.  

 

To get the percentile for Temperature for Baxley weather station, I used
the following 2 statements. 

> BaxleyList[1] <- data.frame(quantile(subset(Data, (Name=='Baxley' &
Temp>-50), select=Temp),probs=seq(0,1,0.01),na.rm=T,names=T))

> colnames(BaxleyList)[1] <- 'Temp'

 

With this success, I want to loop through the station list.  But, I ran
into problem in the variable name "BaxleyList".  

 

I tried the following: 

#StationNames

> StationNameList <- unique(Data$Name)

 

> for (i in 1:1)

{

ThisStation <- StationNameList[i]

ThisStationList <- paste(ThisStation,'List',sep="")

ThisStationList[1] <- data.frame(quantile(subset(Data,
(Name==ThisStation & Temp>-50),
select=Temp),probs=seq(0,1,0.01),na.rm=T,names=T))

colnames(ThisStationList)[1] <- 'Temp'

}

 

But, ThisStationList will not give me BaxleyList.  

 

Thank you for all your helps in advance!
