How to insert axis label in beta diversity #1210

Closed bioinfonext closed 5 years ago

bioinfonext commented 5 years ago

Hi,

could you please suggest me, how can insert axis label as PC1 and PC2 with percent of variance in the below code.

Now It is showing label as Axis1 (20%), Axis2(13%), I want PC1 and PC2 instead of axis.

phyloseq_prop = transform_sample_counts(ps5, function(x) 1E6 * x/sum(x))

phyloseq_prop_bray <- ordinate(phyloseq_prop, "PCoA", "bray") p=plot_ordination(phyloseq_prop,phyloseq_prop_bray, color = "Treatment", shape="Villages") p = p + geom_point(size = 4, alpha = 0.75) p + ggtitle("PCoA 16S data, Bray distance")

Thanks

You can make use of the labs function of ggplot2.

p + ggtitle("PCoA 16S data, Bray distance") + labs(x='PC1 [%?]', y='PC2 [%?]')
