This should be very simple but I am wrestling with updating a data frame from
within a function. Here is a simple example:
### SET UP DATA FRAME
> tFrame <- data.frame(T=c(1:5))
>
> tFrame
T
1 1
2 2
3 3
4 4
5 5
>
##### Simple function that updates with 1000
> tUpdate<- function (x){
+ tFrame$T[x] <- 1000
+ }
> tUpdate(5)
> tFrame
############# Update within function fails
T
1 1
2 2
3 3
4 4
5 5
>
######## Update dataframe outside function with 100
> tFrame[5,1] <- 100
> tFrame
T
1 1
2 2
3 3
4 4
5 100
