Function to classify RNA-seq gene expression profiles using support vector machines (SVM)
1 | classifyProfile.rnaseq.svm(ref_matrix, query_mat, gene.ids.type="ensembl", fun1 = median)
|
ref_matrix |
RNA-seq data matrix to be used as reference, with genes corresponding to rows and samples corresponding to columns. |
query_mat |
RNA-seq query matrix to be classified, with genes corresponding to rows and samples corresponding to columns. |
gene.ids.type |
Type of the used gene identifiers, the following gene identifiers are supported: ensembl, refseq and ucsc gene ids. Default is ensembl. |
fun1 |
mean or median. This will specify the number of marker genes that will be used for classification. Default is median. |
This function is based on the function svm from the R-package 'e1071'.
A data frame with the predicted classes for each query profile.
