Pfadanalyse mit piecewiseSEM "Error"

Beitragvon eimichae » Do 3. Nov 2022, 12:43

Hallo zusammen,
Ich möchte eine Pfadanalyse mit dem R-package piecewiseSEM durchführen.
Ich habe eine vereinfachtes Modell nach dem Beispiel das in der piecewiseSEM Beschreibung gegebenwurde Sturkturiert.
Leider kriege ich bei der Anwendung des "as.psem" Befehls folgenden Error: "Error in `[.data.frame`(x$data, , vars) :
nicht definierte Spalten gewählt". Ich habe meine Daten mehrfach durckämmt und die Modelle angeschaut. Alles sollte ok sein. Kann mir da jemand weiterhelfen? Wieso kriege ich den Error:

Untenstehend mein Code und das Datenset:
Besten Dank
Michi
Code: Alles auswählen
data2$Tree.ID<-as.factor(data2$Tree.ID)
data2$Year<-as.factor(data2$Year)
data2$Drought<-as.factor(data2$Drought)
data2$Stratum<-as.factor(data2$Stratum)

CODE:

# 1x:
mod1x<-lmer(N_pc~Stratum:Drought+Year:Drought+(1|Tree.ID),data2)

mod11a<-glmer(cbind(branch_suck_Yes,branch_suck_No)~N_pc+(1|Tree.ID),
              data=data2, family = binomial(link = "logit"))
modlist = list(
  mod1x, mod11a)
model<-as.psem(modlist)#Error: Error in `[.data.frame`(x$data, , vars) : undefined columns selected

model<-psem(modlist, data2)
coefs(modlist, data2, standardize = "none", intercept = FALSE)
model<-psem(mod1x, mod11a)
