summary statistics into table/data base, many factors to analyse
Dear list,
I reduced my data to the following:
x <- c(1,4,2,6,8,3,4,2,4,5,1,3)
y <- as.factor(c(2,2,1,1,1,2,2,1,1,2,1,2))
z <- as.factor(c(1,2,2,1,1,2,2,3,3,3,3,3))
I can produce the statistical summary just fine.
s1 <- tapply(x, y, summary)
d1 <- tapply(x, y, sd)
s2 <- tapply(x, z, summary)
d2 <- tapply(x, z, sd)
First thing:
I have 100 plus factors to analyse. Theirs
