Good day,
A function is used on a database with 50 rows and 200 collumns. every row is 1
seperate study that the function should run through. Desired outcome are [x,y]
and a weight for that coordinate.
I have problems with generating x.
## Generating random time or x coordinate (through random time of displacement
- random recall)
## First generating random time within recall period
randomrecall<-round(runif(n=1,min=recallmin,max=recallmax))
## Second generating random time of displacement
todrange<-todmax-todminrandomtod<-0for(i in 1:todrange){if
(proprand>data[[9+i]] & proprand<=data[[10+i]]) randomtod=i}
Following messages are given:
Warning messages:1: In 1:todrange : numerical expression has 50 elements: only
the first used2: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be used3: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be used4: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be used5: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be used6: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be used7: In if (proprand > data[[9 + i]] & proprand <= data[[10 + i]])
randomtod = i : the condition has length > 1 and only the first element will
be!
used
#Thusx<-randomtod-randomrecall
----------------------------------------------------------------------------------
Question:
1. how to avoid the warning messages and make the function use all 50 elements?
x will now go through the first row, because it uses the first element,
giving only 1 outcome. But I would like it to give 50, just like the
other variables in the function. How can I do that?
Thank you,
Akko
