[R-marketing-bugs] Bug. p16?

[Chris Chapman]

(copying from separate thread)

It looks like you may need to specify the SEM model on 3 lines instead of a
single line. Just hit ENTER after "iSalesSAT" on the first line and R will
create a new line with "+" for you to continue.

Here's a direct copy from the R console:

> satModel <- "SAT =~ iProdSAT + iSalesSAT
+              REC =~ iProdREC + iSalesREC
+              REC ~  SAT "

> library(lavaan)
> sat.fit <- cfa(satModel, data=satData)
> summary(sat.fit, fit.m=TRUE)
lavaan (0.5-17) converged normally after  31 iterations
...

Also, just to check, make sure that you've loaded "satData". You could
check that with summary(satData)

Best,
