Hello R help list,
I am using the mda package and in particular the fda routine to classify a
set of 4409 trips.
I preformed a flexible discriminant analysis (FDA) using a set of 148
trips. A total of 36 predictors were considered. the resulting FDA rule was
applied to the 4409 trips and for the same predictors in order to predict
to which group the trip will belong. A consistent error is occuring:
Error in mindist[l] <- ndist[l] :
NAs are not allowed in subscripted assignments
script:
matriz <- read.table("matriz2010.txt", header=T,
sep="\t")
names(matriz)
matrizR <- matriz[,-c(1:9, 11:15, 32, 35, 36, 47, 50, 51, 56)]
names(matrizR)
matrizRR <- matrizR[,-c(2:7)]
names(matrizRR)
SKA <- read.table("SKA.txt", header=T, sep="\t")
names(SKA)
matrizRRSKA <- cbind(matrizRR, SKA)
names(matrizRRSKA)
summary(matrizRRSKA)
#discriminant analysis
FDAaSKA <- fda(as.factor(ARTE_resumida) ~ . , data =matrizRRSKA)
FDAaSKA
plot(FDAaSKA)

matrizT <- read.table("matriz2010tot.txt", header=T,

names(matrizT)
summary(matrizT)
dim(matrizT)
matrizTR <- matrizT[,-c(1:6, 17, 20, 21, 32, 35, 36)]
names(matrizTR)
predict(FDAaSKA, matrizTR)$class
Error in mindist[l] <- ndist[l] :

if someone can help, would be very grateful.
cheers,
Catarina
