Object item extraction
Any R output is an object you can manipulate basically using exctractions functions $, [ and [[ To look at the content of the object, try:
str(model)
And (in this case)
str(summary(model))
Then you can extract what you need, such as:
summary(model)$adj.r.squared
[1] 0.02158191 (an other model...) 1.419101 1.000000 18.000000
summary(model)$fstatistic
value numdf dendf 1.419101 1.000000 18.000000
summary(model)$fstatistic[["value"]]

(Robin) (IenT) Sent: lundi 4 avril 2005 10:36 To: r-help at stat.math.ethz.ch Subject: [R] Object item extraction Hello I am able to extract partial regression coefficients from a fitted model object "model", i.e. model <- lm(var.sel.gkm, weights = count.gkm, data = DATA) summary(model) write.table(model$coef, file = "C:/coef_CO_gkm.txt", row.names = TRUE, col.names = TRUE) I was wondering if anyone could advise me how to extract other object items such as std. error, t-values and adjusted R2 in the same way.
