Hello,
I wonder if I ran into a bug. If I do
summary(df1$X1) -> df1.y
df1.y
a b c d e
[1,] 50.74627 8.955224 17.91045 19.40299 2.985075
sort(df1.y)
a b c d e
[1,] 2.985075 8.955224 17.91045 19.40299 50.74627
my numbers are sorted but do not anymore correspond to the rownames.
For me it is counterintuitive that solely the numbers are sorted and not the
names. Is there a way to sort names + numbers or is this behaviour of sort()
unintended?

sort() leaves row names unaffected

Note: You are sorting a matrix rather than a vector!

You mean colnames, not rownames!

Don't use sort() on matrices, use order() instead, as in: x[,order(x)] Uwe Ligges

Hi I am not sure how you did get such result of sort and summary Summary usually gives
summary(titr$kys)
Min. 1st Qu. Median Mean 3rd Qu. Max. 0.000 1.050 1.250 1.143 1.369 2.000 and sorting it
y<-summary(titr$kys) y[1]<-5 y[3]<-10 y
Min. 1st Qu. Median Mean 3rd Qu. Max. 5.000 1.050 10.000 1.143 1.369 2.000
sort(y)
1st Qu. Mean 3rd Qu. Max. Min. Median 1.050 1.143 1.369 2.000 5.000 10.000 as well as
x<-rnorm(5)*5 names(x)<-letters[1:5] x
a b c d e -3.8849080 1.9393499 1.8456569 -2.5334288 0.6304933
sort(x)
a d e c b -3.8849080 -2.5334288 0.6304933 1.8456569 1.9393499
