Dataframes: conditional calculations per row .
...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
different structure depending on the values of llmcc$Clase, thus: for
any given row of llmcc where llmcc$Clase is >= 10 i would have to
perform some operations with other values in the same row that are,...
