I want to replace 0 (missing data) with data from another array.
Both data has 2013~1995 January ice sheet data, and I want to analyze temperature data only (in column 3), 4464 temperatures data.
Partial data looks like this: This is from ErinJan[,,1]
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1 ,] 21 10 0.0 0.0 0.0 0 0.0 0
[2 ,] 21 11 0.0 0.0 0.0 0 0.0 0
[3 ,] 21 12 -16.3 867.4 0.0 0 0.0 0
[4 ,] 21 13 -16.4 867.5 6.9 81 63.2 0
[5 ,] 21 14 -16.5 867.2 7.6 83 63.0 0
[6 ,] 21 15 -16.5 867.1 7.9 84 63.0 0
[7 ,] 21 16 0.0 867.1 8.0 86 62.0 0
[8 ,] 21 17 -16.3 867.0 8.4 87 62.0 0
[9 ,] 21 18 0.0 866.9 8.3 85 62.0 0
And HarryJan[,,1] looks like:
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1 ,] 21 10 -12.4 877.6 2.5 52 444.0 9.1
[2 ,] 21 11 -12.6 877.6 3.0 55 444.0 9.1
[3 ,] 21 12 -12.9 877.5 3.8 52 444.0 9.1
[4 ,] 21 13 -13.0 877.5 3.6 53 444.0 9.1
[5 ,] 21 14 -12.9 877.3 3.3 51 444.0 9.1
[6 ,] 21 15 -13.0 877.3 4.1 53 444.0 9.1
[7 ,] 21 16 -13.2 877.1 3.6 53 444.0 9.1
[8 ,] 21 17 -13.4 877.3 3.3 45 444.0 9.1
[9 ,] 21 18 -13.4 877.3 3.6 48 444.0 9.1
Both array has the same format and same type of data like above. My goal is replace ErinJan[,3,1] missing data with HarryJan[,3,1] and so on. For example, ErinJan[1,3,1] is missing data, so I need to replace with HarryJan[1,3,1]. (0 will be replaced with -12.4.)
If I can code something like this:
for (i in 1: 19){
if ErinJan[,3,i] == 0 {
replace value using HarryJan
}
else {
do nothing
}
}
Is this possible? I am not sure what command I should use. Replace
?
I'd appreciate your help.
