Hi

Of course you have fewer values than in original data.
[1] 19
[1] 21
[,1] [,2] [,3]
[1,]    3    2    1
[2,]    4    3    2
[3,]    5    4    3
[4,]    6    5    4
[5,]    7    6    5
[6,]    8    7    6
[7,]    9    8    7
[8,]   10    9    8
[9,]   11   10    9
[10,]   12   11   10
[11,]   13   12   11
[12,]   14   13   12
[13,]   15   14   13
[14,]   16   15   14
[15,]   17   16   15
[16,]   18   17   16
[17,]   19   18   17
[18,]   20   19   18
[19,]   21   20   19

You need to prepend or append 2 NA values if you want to add newly computed values to old data.

or extend your original vector by 2 values

length(rowSums(embed(c(NA, NA, x),3), na.rm=T))
[1] 21

Upon trying this method, I get an error ;

Error in `$<-.data.frame`(`*tmp*`, "MEImeans", value = c(0.313162987462034,  :
  replacement has 442 rows, data has 444
Any thoughts?

Hi

Probably just a small correction.

d3 <- embed( dta$MEI, 3)
