Help in kmeans
...y application we generate
the R commands dynamically and there was a requirement that the column names
will be sent instead of column indices to the R commands.Hence, to
incorporate this, i tried using the R commands in the following way.
kmeans_model<-kmeans((SepalLength+SepalWidth+PetalLength+PetalWidth),centers=3)
or
kmeans_model<-kmeans(as.matrix(SepalLength,SepalWidth,PetalLength,PetalWidth),centers=3)
In both the ways, we found that the results are different from what we saw
with the first command (with column indices).
can you please let us know what is going wrong here.If so, can you...
