Dear all,
The following example in the package of knncat run well in R, so we
hope to cluster our data just following this. The problem is how to
import the data, how to build the vector and matrix? The first collumn
should be the indentifier? the second collumn should be the expression
average? and the third collumn should be the classifier? The data
should be imported as a text file, Excel file or other type of file?
Any clue? Thanks a lot!
library(MASS) # Load data set
syncat <- knncat synth.tr, classcol=3)
## Not run:
syncat
Train set misclass rate: 16.8
synpred <- predict (syncat, synth.tr, synth.te, train.classcol=3,
newdata.classcol=3)
table (synpred, synth.te$yc)
synpred 0 1
0 466 61
1 34 439
#
# Or do the whole thing in one pass:
#
## End(Not run)
knncat synth.tr, synth.te, classcol=3)
## Not run:
Test set misclass rate: 9.5
## End(Not run)
