[R] Error in for-loop

[Domi]

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. 

Best regards,

Domi
