Calculating variables
Dear fellows: This is the problem: I have 5 variables A, B, C, D and E
with a range from 1 to 100 with 0.1 steps. Depending on the different
values these have, the results of the formula change:
alitemp <- ((Abase/llmcc$Clase)*PClase)+(((1/llmcc
$Categoria)*Abase)*PCategoria)+((Abase*llmcc$Phi)*PPhi)+((Abase*llmcc
$Rf)*PRf)
So, alitemp (a 283 element series) changes if any of the P** values
changes. I need to find a combinations of those 5 variables that
approximates the desired results. Although I can make use of a 'for'
loop, Im not sure of how to com...

Dataframes: conditional calculations per row .

$ NewA_Jon : num 1.069 0.368 0.256 0.256 0.264 ...
I perform an initial operation using the original variables plus one
numeric (Abase) that is external and has the same number of rows than
the dataframe:
alitemp <- ((Abase/llmcc$Clase)*PClase)+(((1/llmcc
$Categoria)*Abase)*PCategoria)+((Abase*llmcc$Phi)*PPhi)+((Abase*llmcc
$Rf)*PRf)
So, after I obtain the results of this calculation, I append the
series by creating an additional column within the original dataframe:
l
lmcc$Alitmp <- alitemp
Problem is: I need to calculate a new column using a formula that has
differe...
