[R] Sem error - subscript out of bounds

[Leonard assis]

What´s happening with this following code:

require(sem)
Celpe.Mod.RAM <- matrix(c(
                       #  path                           parametro    Inicio
                          "Produção    ->  T1",          "gamma.11",  NA,
                          "Produção    ->  T2",          "gamma.12",  NA,
                          "Produção    ->  T3",          "gamma.13",  NA,
                          "Produção    ->  T4",          "gamma.14",  NA,
                          "Compreensão ->  T1",          "gamma.21",  NA,
                          "Compreensão ->  T2",          "gamma.22",  NA,
                          "Compreensão ->  PI",          "gamma.23",  NA,
                          "Certificado ->  Produção",    "alpha.11",  NA,
                          "Certificado ->  Compreensão", "alpha.12",  NA,
                          "Compreensão <-> Produção",    "alpha.21",  NA
                          ),
                        ncol=3, byrow=TRUE)

Celpe.cov <- cov(Celpe.Dados.Fatorial[3:7])
Celpe.cfa.sem <- sem(ram=Celpe.Mod.RAM, S=Celpe.cov,
N=1443,refit=TRUE,debug=TRUE)

Here comes the Results:
