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 -- View this message in context: http://www.nabble.com/creating-a-new-vecotr-in-a-for-loop-tp20691663p20691663.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
