Hi,

dat1$confused<- 1*((dat1$race==1|dat1$race==2) & dat1$usborn==0)
head(dat1)

Colleagues,
I am in the process of learning R. I've been able to import my dataset (from

able to execute in R:

This message could be useful for people fairly new to S4 classes.

One use for showMethods(), important to me,

Dear All,
Can somebody explain me how to correctly set a new class-specific method
for generic functions (e.g. for "plot", "summary" and "print"). I simply
programmed these functions with the class names and it works perfectly.
E.g.:
x<-2
y<-3
class(x)<-"newclass"
class(y)<-"newclass"

Hi Ira,
Some suggestions:
1. Not sure why you created a dataframe with NA's in the beginning. It seemed
to be not required here.
df1 = data.frame(matrix(rep(NA, 10*7), nrow = 10))
2. The below code:
df1 = data.frame(Dates = Dates, P1 = P1, P2 = P2, OF1 = OF1, OF2 = OF2)
can be simplifed as:
df1
If you say something inn public, it will be there and people may
remember it - you can't take back what you said.
So why is a mailing list different? it is just that we are typing
instead of talking - it goes into the public and there it stays.
Ever heard of the Streisand effect

Note that your inner loop
> for(i in 1:10 ) {
>rowNumber = i + df1[i,j-2]
>df1[i,j] = df1[rowNumber, j-4]
> } # end i loop
is equivalent to the much quicker
i <- 1:10
rowNumbers <- i + df1[i, j-2]
df1[i, j] <- df1[rowNumbers, j-4]
