Hi R users,
Is there an easy way in R to generate the results table below using table 1
and the formula (simplified version of the real problem)? It would be easy
if I knew the R equivalent of SAS's retain function, but could not find one.
Thanks in Advance for any help!
table1:
ID X2
Dear Pele,
Probably not the best way to proceed but it works:
X-read.table(textConnection(ID X2
1.001.00
2.000.00
3.001.00
4.003058
5.000.00
6.006.00),header=TRUE)
closeAllConnections()
X
x3-0
for(i in 2:(nrow(X)+1)) x3-c(x3, X$X2[i-1]+0.24*x3[i-1])
X$x3-x3[-1]
X

Hi Jorge - many thanks for you suggestion, but I am looking
for a way where I don't have to use a loop. I meant to
include that in my description.
Thanks again!
