Description Usage Arguments Value Examples
This is a flexible t-SNE function that can be run on a standard data frame. It is a wrapper for Rtsne/ggplot2 code and can be customised with different colours and font sizes and more.

|
mydata |
Data frame or matrix: if dataframe/matrix should have samples as columns and rows as features |
labels |
Character vector: if we want to just label with gender for example |
perplex |
Numerical value: perplexity value that Rtsne uses internally |
printres |
Logical flag: whether to print the t-SNE into current directory |
seed |
Numerical value: optionally set the seed |
axistextsize |
Numerical value: axis text size |
legendtextsize |
Numerical value: legend text size |
dotsize |
Numerical value: dot size |
textlabelsize |
Numerical value: text inside plot label size |
legendtitle |
Character vector: text legend title |
controlscale |
Logical flag: whether to control the colour scale |
scale |
Numerical value: 1=spectral palette, 2=manual low and high palette, 3=categorical labels |
low |
Character vector: continuous scale low colour |
high |
Character vector: continuous scale high colour |
colvec |
Character vector: a series of colours in vector for categorical labels, e.g. c("sky blue", "gold") |
printheight |
Numerical value: png height |
printwidth |
Numerical value: png width |
text |
Character vector: if we wanted to label the samples with text IDs to look for outliers |
