Dear All,
i am solving the following problem in my work.
The first day from April 01 that gets more than 20 mm on a single day, or
totalled
over 2 consecutive days. i.e April 01 = 92th day of the year.
The column of interest is "Rain".
> head(Samaru56)
Year Day Rain
1 1928 1 0
2 1928 2 0
3 1928 3 0
4 1928 4 0
5 1928 5 0
6 1928 6 0
I used the loop below but it is not printing anything.
sow_day=c()
for (i in 1928:1983){
for (j in 92:366){
k=j-1
s_rain=Samaru56$Rain[k] + Samaru56$Rain[j]
if (s_rain>=20)
sow_day=j
break
}
Samaru56$year=Samaru56$Year[sow_day]
Samaru56$Day=Samaru56$Day[sow_day]
Samaru56$Rain=Samaru56$Rain[sow_day]
}
sow_day
Any idea is welcome on how I can solve this problem. Thanks
