Examples

# 1. Library TOmicsVis package
library(TOmicsVis)

# 2. Use example dataset
data(gene_expression)
head(gene_expression)

data(samples_groups)
head(samples_groups)

# 3. Default parameters
tsne_plot(gene_expression, samples_groups)

# 4. Set sci_fill_color = "Sci_NPG", seed = 6
tsne_plot(gene_expression, samples_groups, sci_fill_color = "Sci_NPG", seed = 6)

# 5. Set multi_shape = TRUE, fill_alpha = 0.00
tsne_plot(gene_expression, samples_groups, multi_shape = TRUE, fill_alpha = 0.00)
