Hello. When one types "summary(fit)", where fit is an object from a
call
to aov(), one gets an ANOVA table. I want to save just one element of this
summary. How does one extract this?
As an example, here is my output from a split plot ANOVA:
> summary(out)$"Error: soil.cores$block:soil.cores$treatment"
Df Sum Sq Mean Sq F value Pr(>F)
soil.cores$block 3 0.63626 0.21209 1.0557 0.4147
soil.cores$treatment 3 0.90276 0.30092 1.4978 0.2802
Residuals 9 1.80813 0.20090
I want to save only the F value of "soil.cores$treatment" . In SPLUS
one
would do this by
summary(out)$"Error: soil.cores$block:soil.cores$treatment"$"F
value"[2]
but this doesn't seem to work.
Thanks.

Is there a simple way to string-concatenate across the rows of a matrix or data.frame into a vector of strings? perhaps using paste() or something like it? That is, I want to map from something like x2 below: > x2 <- data.frame(C1 = letters[1:4], C3=1:4, C3=letters[11:14]) > x2 C1 C3 C3 1 a 1 k 2 b 2 l 3 c 3 m 4 d 4 n to something like: [1] "a 1 k" [2] "b 2 l" [3] "c 3 m" [4] "d 4 n" Sincerely, Al Kim Research Scientist Department of Psychology University of Washington, Box 351525 Seattle, WA. 98195, USA E-Mail: alkim at u.washington.edu; Tel: (206)543-2395 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
