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

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

The "confusionMatrix" function appears to be from the 'caret' package.
Have you loaded 'caret' with the library(caret) command?

The standard approach for prediction is via a predict() method for the
class of the model fit. So, have you checked
?predict.naiveBayes
If this does not satisfy your needs, you are on your own. Possibly your
best course of action then is to contact the maintainer as the posting

Dear list,
I fit a multivariate model and want to extract univariate confidence
intervals from the mlm object. If the response matrix is unnamed,
confint() just repeats the first interval. If the response matrix is
named, confint() correctly returns CIs for all columns:
set.seed(1143)
Y <- MASS:

R typically asks you if you want to save your workspace when you quit. If you
say yes, your global environment is saved to a file called ".RData" in your
current working directory. When you start R it looks for a file of this name in
the current working directory and silently loads it.

Is there a better way than grabbing individual cell values from a model
output to make predictions. For example the output from the following Naïve
Bayes model

## Example of using a contingency table:
data(Titanic)
m <- naiveBayes(Survived ~ ., data = Titanic)

Good morning!
Each time I open a new R session, it appears the same objects that I
thought were removed on an old session, but the objects I supposed were
saved on the last session never appeared.
Thanks!
