[R] aov summary to matrix
Is there an easy way of converting an aov.summary into a matrix in which the rows are the factor names and the columns are Df, Sum Sq, Mean Sq, F value and Pr. For example, convert Df Sum Sq Mean Sq F value Pr(F) block5 343.29 68.66 4.4467 0.015939 * N1 189.28 189.28 12.2587 0.004372 ** P1 8.408.40 0.5441 0.474904 K1 95.20 95.20 6.1657 0.028795 * N:P 1 21.28 21.28 1.3783 0.263165 N:K 1 33.14 33.14 2.1460 0.168648 P:K 1 0.480.48 0.0312 0.862752 Residuals 12 185.29 15.44 --- Signif. codes: 0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` ' 1 To Factor Df Sum Sq Mean Sq F value Pr block5 343.29 68.66 4.4467 0.015939 N1 189.28 189.28 12.2587 0.004372 P1 8.408.40 0.5441 0.474904 K1 95.20 95.20 6.1657 0.028795 N:P 1 21.28 21.28 1.3783 0.263165 N:K 1 33.14 33.14 2.1460 0.168648 P:K 1 0.480.48 0.0312 0.862752 Residuals 12 185.29 15.44NA NA Thanks, - Moises __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

You are confusing the printed representation with the object (which seems today's favourite misconception). as.matrix(summary(npk.aov)[[1]]) is a matrix (to full precision) as you seek, although I would prefer to work with the data frame which is returned. (Note: your output is from MASS4 example(aov), unattributed.) For example, convert Df Sum Sq Mean Sq F value Pr(F) block5 343.29 68.66 4.4467 0.015939 * N1 189.28 189.28 12.2587 0.004372 ** P1 8.408.40 0.5441 0.474904 K1 95.20 95.20 6.1657 0.028795 * N:P 1 21.28 21.28 1.3783 0.263165 N:K 1 33.14 33.14 2.1460 0.168648 P:K 1 0.480.48 0.0312 0.862752 Residuals 12 185.29 15.44 --- Signif. codes: 0 `***' 0.001 `**' 0.01 `*' 0.05 `.' 0.1 ` ' 1 To Factor Df Sum Sq Mean Sq F value Pr block5 343.29 68.66 4.4467 0.015939 N1 189.28 189.28 12.2587 0.004372 P1 8.408.40 0.5441 0.474904 K1 95.20 95.20 6.1657 0.028795 N:P 1 21.28 21.28 1.3783 0.263165 N:K 1 33.14 33.14 2.1460 0.168648 P:K 1 0.480.48 0.0312 0.862752 Residuals 12 185.29 15.44NA NA -- Brian D.

Try this:
example(aov)
as.data.frame.summary.aovlist - function(x) {
if(length(x) == 1) {
as.data.frame(x[[1]])
} else {
lapply(unlist(x, FALSE), as.data.frame)
}
}
x1 - summary(npk.aov)
x2 - summary(npk.aovE)
as.data.frame(x1)
as.data.frame(x2)
