[R] Multiple Line Widths denextend

[Worthington, Thomas A]

Dear All 

We are using the dendextend package to modify the plot output from a pvclust clustering 

The model is created with 

result <- pvclust(chord.1, method.dist="euclidian", method.hclust="average",nboot=100000)

The plot is then formatted as following 

dend <- as.dendrogram(result)
dend %>%
pvclust_show_signif(result, signif_type = c("au"),alpha=0.05, signif_value = c(4, 1)) %>% set("labels_cex", c(1.5)) %>% set("labels_col", sp_col) %>% 
plot(horiz=TRUE, sub="", xlab="", ylab="",xlim=c(0.31, -0.17), ylim= c(3.5,93))

We are using the pvclust_show_signif function to set the line weight to '4' of pvclust branches with an alpha of less than 0.05. Is it possible to set multiple line weights for different alpha values e.g. lwd = 8 when alpha = 0.05 and lwd = 4 when alpha = 0.1?

Best wishes
Tom
