I have consulted the intro and nabble but have not found an answer to what
should be a simple question, here goes:
I am doing a crosscheck of a data frame and pulling out a single value based
on an inputted value ie based on x i will select y, or if x =2 then my code
returns 7.
x y
1 4
2 7
3 10
4 2
My code currently iterates through for as many times as the length of the x
dataframe. What i would like to do is then is to build a vector for those
values selected. so if vector x = 1,4,7 then "new-y" would equal 4, 2, 3.
x y
1 4
2 7
3 10
4 2
5 21
6 13
7 3
8 90
I need to ultimetly re-sort my x vector based on the values of y but the
function i am using is the subset function and i cant do it without y being
a vector itself and it is currently only a one value object.
#Creates test Candidates Vector
Candidates=c(100,101,102,103,104,105)
#Creates object equaling the number of candidate TAZs from the main script
Location Choice Model
NumCands1=length(Candidates)
Dev..At=9999999
for(i in 1:NumCands1){
#Renames Location Choice Model generated TAZ's object
Loc_Mod_TAZ=Candidates[i]
#Converts Development size from main script to Development density
function
format
Dev_Size=Dev..At
#This is my "y" value in the example i gave above, this is the value
that i
need put into a # vector, a vector that should have as
many values as there are number of candidates
TAZDetermine_FEET=TAZ_VAC_FEET[TAZ_VAC_FEET$TAZ==Loc_Mod_TAZ,2]
#Creates new vector based on adaquate vacancy in the TAZ and the
development to be located
Newcands=subset(Loc_Mod_TAZ, TAZDetermine_FEET>=Dev_Size)
}
Thanks for the help
Cheers,
JR
