give a principal component, tells you which contribute the most or give a sample, tells you which PC's it contributes to the most
plot_loadings(obj, use_filtered = TRUE, sample = NULL, pc_input = NULL, units = "est_counts", pc_count = NULL, scale = FALSE, pca_loading_abs = TRUE, ...)
obj |
a |
use_filtered |
if TRUE, use filtered data. otherwise, use all data |
sample |
a character string representing the sample to find the loadings of. If NULL, then loadings will be computed across all samples (and 'pc_input' must be specified). |
pc_input |
the principal components to compute loadings for. |
units |
either 'est_counts' ('scaled_reads_per_base' for gene_mode) or 'tpm' |
pc_count |
# of PC's |
scale |
scale or not |
pca_loading_abs |
default true, to see all PC's magnitude (recommended) |
