Hello,
this little example my work for demo purposes:
x1 = runif(45)
x2 = runif(45)
x3 = runif(45)
df = data.frame(x1=x1,x2=x2,x3=x3)
test <- function(df, values, n) {
if (nrow(df) < n) {
df <- rbind(df, values)
} else {
df[1:(nrow(df)-1),] <- df[2:nrow(df),]
df[n,] <- values
}
return(df)
}
my dataset looks like :
>df
VIX GLD FAS
12 4 5
28 9 10
356 9 98 .. continued
the dataset has n observations which is fixed and i need to create a
function :
test <- function(variable name, value) -- this function has to insert the
value under the re
2 matches
