geneUsageAnalysis {immunarch} | R Documentation |
Post-analysis of V-gene and J-gene statistics: PCA, clustering, etc.
Description
The geneUsageAnalysis
function deploys several
data analysis methods, including PCA, multidimensional scaling,
Jensen-Shannon divergence, k-means, hierarchical clustering, DBscan, and different
correlation coefficients.
Usage
geneUsageAnalysis(
.data,
.method = c("js+hclust", "pca+kmeans", "anova", "js+pca+kmeans"),
.base = 2,
.norm.entropy = FALSE,
.cor = c("pearson", "kendall", "spearman"),
.do.norm = TRUE,
.laplace = 1e-12,
.verbose = TRUE,
.k = 2,
.eps = 0.01,
.perp = 1,
.theta = 0.1
)
Arguments
.data |
The |
.method |
A string that defines the type of analysis to perform. Can be "pca",
"mds", "js", "kmeans", "hclust", "dbscan" or "cor" if you want to calculate
correlation coefficient. In the latter case you have to provide |
.base |
A numerical value that defines the logarithm base for Jensen-Shannon divergence. |
.norm.entropy |
A logical value. Set TRUE to normalise your data if you haven't done it already. |
.cor |
A string that defines the correlation coefficient for analysis. Can be "pearson", "kendall" or "spearman". |
.do.norm |
A logical value. If TRUE it forces Laplace smoothing, if NA it checks if smoothing is necessary, if FALSE does nothing. |
.laplace |
The numeric value, which is used as a pseudocount for Laplace smoothing. |
.verbose |
A logical value. |
.k |
The number of clusters to create, passed as |
.eps |
A numerical value, DBscan epsylon parameter, see
|
.perp |
A numerical value, t-SNE perplexity, see |
.theta |
A numerical value, t-SNE theta parameter, see |
Value
Depends on the last element in the .method
string. See immunr_tsne for more info.
Examples

gu <- geneUsage(immdata$data, .norm = TRUE)
