Error in as(x, "matrix")[i, j, drop = FALSE] :

[SilviaSalgar]

Hi Everyone,
I am using the following command to obtain alpha diversity of my samples

p<-plot_anova_diversity(physeq, method = c("richness","simpson", "shannon", "evenness"), grouping_column = "Ballast_Tank", pValueCutoff=0.05, outfile = "anova_diversity.csv")

But I am getting the following error

Error in as(x, "matrix")[i, j, drop = FALSE] :
(subscript) logical subscript too long

Suggestions are welcome :)
