I have to admit that I’m not quite sure what is happening in your case. But, I noticed that somehow I forgot to push a batch of tsne changes to CRAN some time ago. So, I’ve dusted them off and sent them in. If you check ftp://cran.r-project.org/incoming, you should see the package I’ve uploaded called tsne_0.1-2.tar.gz. If it’s not there, then it’s probably already available on CRAN.

If you continue to have problems, feel free to send me a note at my e-mail address listed in the tsne docs.

P.S. I’ve also added the code for this package to a repo on github: https://github.com/jdonaldson/rtsne

I am using the R implementation of t-SNE, thank you for writing it. I got it to work once, but now have a recurring problem.

Namely, the error:
Error in while (abs(Hdiff) > tol && tries < 50) { :
missing value where TRUE/FALSE needed

Using the command with an object of class='dist' produced the same error. To work around that I did this:
nbsed.df <- data.frame(as.matrix(nbsed))

Which worked once, but not on the second data set.

nbsed.tsne tol && tries < 50) { :
missing value where TRUE/FALSE needed

Any attempts to change any of the parameters results in an error. I have been in touch with Laurens. I followed the link on the t-SNE website to post to this website.

Thanks for your help,
