This gives the error shown.

library(qeML)
set.seed(123)
ix <- sample(10, 15, replace = TRUE) + seq(1, 150, 10) - 1
iris.ix <- iris[ix, 1:4]
qeKNN(iris.ix, "Petal.Length", k = 1)
## Error in `[.data.frame`(tst, , ycol) : undefined columns selected

Note that this works without error:

library(qeML)
set.seed(123)
qeKNN(iris[1:4], "Petal.Length", k = 1)
# ...snip...

and this too:

library(FNN)
set.seed(123)
ix <- sample(10, 15, replace = TRUE) + seq(1, 150, 10) - 1
iris.ix <- iris[ix, 1:4]
knn.reg(iris.ix[-4], y = iris.ix[[4]], k = 1)
## PRESS =  0.44 
## R2-Predict =  0.9511979 

[matloff]

Yes, fixed in Version 1.2.
