如何在使用 R 进行因子分析 (psych:fa) 后获得 RMSEA 值？

Question

I did a factor analysis on a database using the fa function of the R psych package:

facto <- fa(df)

I managed to retrieve the RMSEA with facto$RMSEA:

For example:

RMSEA	lower	upper	confidence
0.08014526	0.07886056	0.08162674	0.90000000

But I would like to retrieve only the first value (0.08). Do you know how to access it?

I don't see the wanted value in the fa function Rdocumentation

Answer 1

I ended up discovering the answer. The RMSEA value is here:

facto$RMSEA[["RMSEA"]]
