Hi,
I have two time series organized in matixes data.1 and data.2.
They have different length and resolution.
matrix data.1
t1 v1
t3 v3
t5 v5
...
matrix data.2
t1 0
t2 0
t3 0
...
desired result:
data.2
t1 v1
t2 0
t3 v3
...
What is the MOST EFFECTIVE way (since the matrixes are very large) to assign the
values of data.1 to data.2 whenever time values are equal?
Thanks for your help,
Helge
P.S: My solution so far:
for ( i in 1 : nrow(data.1) )
{
index <- which ( data.2[,1] == data.1[i,1] )
data.2[index,2] <- data.1[i,2]
}
