In R Script, for instance in usage of;

regression=lm(a~b)

As known, result of linear model regression can be summarized by

summarize(regression)

In this sample regression variable is a vector which have sub variables an it can be retrieve calling regression['subvariable name'] or regression[subvar number].

I couldn't retrieve the p-value of this model. It's shown in summary output but it couldn't extract from vector.

Calling in names() function breaks down subvariables but some of subvariable have nested values. So i couldn't find them one by one.

Is there any way?

`summary(lm(a~b))$coefficients[, 4]` Or you call the column explicitly by `summary(lm(a~b))$coefficients[, "Pr(>|t|)"]` – David Arenburg Dec 22 '14 at 18:06

Very thanks Mr. Arenburg, it works nicely but throws titles even i call summary(lm(a~b))$coefficients[, 4][1]. But i need only numeric value. – Suat Atan PhD Dec 22 '14 at 18:12

`unname(summary(lm(a~b))$coefficients[, 4])` or `as.numeric(summary(lm(a~b))$coefficients[, 4])` – David Arenburg Dec 22 '14 at 18:13
It works. Thanks again. R is immense. – Suat Atan PhD Dec 22 '14 at 18:14
