rect.dendrogram text labels misplacement with horiz = TRUE

[aravind-j]

Position of text labels by the text = argument in rect.dendrogram is on the horizontal axis rather than the vertical axis when horiz = TRUE.

dend15 <- c(1:5) %>% dist %>% hclust(method = "average") %>% as.dendrogram

par(mar=c(5, 5, 5, 5))

dend15 %>% plot(main="dend15")
dend15 %>% rect.dendrogram(k=3, 
                       border = 8, lty = 5, lwd = 2, text = as.roman(1:3))

dend15 %>% plot(main="dend15", horiz = TRUE)
dend15 %>% rect.dendrogram(k=3, horiz = TRUE,
                       border = 8, lty = 5, lwd = 2, text = as.roman(1:3))

Hi, I have an issue when i use rect.dendrogram() with the text option everything goes fine, however, when I use the option horiz = TRUE text labels do not flip with the dendrogram. Any clues?
Thanks

Thanks everyone for reporting.
I'm not getting to look into it. But if someone would happen to fix it with a PR I'll be happy to review and merge ot.

For future reference, here is how the bug looks like:

dend15 <- c(1:5) %>% dist %>% hclust(method = "average") %>% as.dendrogram

par(mfrow = c(1,2))

dend15 %>% plot(main="dend15")
dend15 %>% rect.dendrogram(k=3, 
                           border = 8, lty = 5, lwd = 2, text = as.roman(1:3))

dend15 %>% plot(main="dend15", horiz = TRUE)
dend15 %>% rect.dendrogram(k=3, horiz = TRUE,
                           border = 8, lty = 5, lwd = 2, text = as.roman(1:3))
