Niny Rao,
It is possible to get the ANOVA table from the sufficient statistics.
The sufficient statistics include the sample sizes which were not included
in the data you posted. I have fake sample sizes n in this example.
You can use the aov.sufficient function in the HH package for this.
install.packages("HH") ## if you don't have HH yet.
library(HH)
nrdata <- read.table(textConnection(
"ID Mean SD 'Coef of Var'
62L 121.60 6.21 5.10
94D 115.92 3.22 2.78
14F 86.51 3.17 3.66
11P 126.71 5.45 4.30
10L 116.67 2.17 1.86
96T 98.20 1.38 1.41
55U 125.93 3.69 2.93
79X 93.73 5.86 6.25
55L 84.24 2.52 2.99
59Q 128.72 0.74 0.58
56S 121.12 1.07 0.89"),
header=TRUE)
nrdata$n <- rep(5, 11) ## fake sample sizes. Real n is needed.
names(nrdata)[3] <- "s" ## required name for within-cell standard deviation
nr.aov <- aov.sufficient(Mean ~ ID, data=nrdata)
summary(nr.aov)
Use
?aov.sufficient
for more information.
