Hello erverybody, I have a problem with my second for-loop.
1. First i read the tables. datos.mx1 <- read.table('PETmx1.csv',head=TRUE,sep=';') datos.min <- read.table('PETmin.csv',head=TRUE,sep=';') http://r.789695.n4.nabble.com/file/n4638257/PETmx1.csv PETmx1.csv http://r.789695.n4.nabble.com/file/n4638257/PETmin.csv PETmin.csv names(datos.mx1) "Fecha" "Mes" "Serra.da.Foladoira" "Santiago" "Sergude" "Rio.Do.Sol" You find in the first column the date and in the second only the month. The other columns contain the temperature of the respective weather stations. 2. My aim is to calculate thresholds for each weather station. superior <- NULL inferior <- NULL LC <- NULL LF <- NULL for (i in 3:6){ superior[i] <- 23+(datos.mx1[i]-23)*0.33; inferior[i] <- 18+(datos.min[i]-18)*0.33; } #Until here everything is ok, but the next loop issues an error. I must multiply the results of each weather station with a constant. for (i in 3:6){ LF[i] <- 1.26086956521739*superior[[i]]; LC[i] <- 0.722222222222222*inferior[[i]] } The error is: "Number of items to replace is not a multiple of replacement length". I hope someone can help me. I thank you very much.
