Using search term "knn classification" on rseek.org brought up many
relevant hits.

Among them,  the knn() function in package "class" seems relevant -- but
there are others, as you will see.

Your second question is about statistics and is largely off topic here. Per
the posting guide (linked below):

"*Questions about statistics:* The R mailing lists are primarily intended
for questions and discussion about the R software. However, questions about
statistical methodology are sometimes posted. If the question is well-asked
and of interest to someone on the list, it *may* elicit an informative
up-to-date answer. See also the Usenet groups sci.stat.consult (applied
statistics and consulting) and sci.stat.math (mathematical stat and
probability)."

However, the rseek.org hits also may be helpful for that. Alternatively,
try stats.stackexchange.com for statistical questions for which you do not
receive a response here.

I have pathogen (1/0) as a dependent variable and total (count) as
independent variable. I have to get 1) KNN on total and 2) get the training
error and training TPR and FPR for k = 5 nearest neighbors using total as a
predictor. and 3) get a plot of training error vs. k for k = 1, 2, ..., 10
with k on the x-axis.

I am not sure how to do this in R. Also, how to know which value(s) of K
would be the most biased in the training error estimate?

Help would be appreciated.

Thanks
