How to replace a column in a data frame with another one with a different size
Hello everyone,
I have a dataframe with 1 column and I'd like to replace that column
with a moving average.
Example:
> library('zoo')
> mydat <- seq_len(10)
> mydat
[1] 1 2 3 4 5 6 7 8 9 10
> df <- data.frame("V1" = mydat)
> df
V1
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
10 10
> df[df$V1 <- rollapply(df$V1, 3, mean)]
