BiocompR is an R package built upon ggplot2, and using data.table. It improves some visualisations commonly used in biology and genomics for data comparison and dataset exploration, introduces new kind of plots, provides a toolbox of functions to work with ggplot2 and grid objects, and ultimately, allows users to customize plots produced into publication ready figures.

❎ Error in UseMethod("depth")
Error in UseMethod("depth") :
no applicable method for 'depth' applied to an object of class "NULL"This error seems to happen randomly when executing code using the ggplot2 and/or grid packages. Usually executing one more time the chunck of code solve the error. The current statues of this issue can be tracked here.
❎ Error in grid.Call(C_convert, x, as.integer(whatfrom), as.integer(whatto), : Viewport has zero dimension(s)
Error in grid.Call(C_convert, x, as.integer(whatfrom), as.integer(whatto), :
Viewport has zero dimension(s)This error can arise when using the ggbipca() function: if you define a legend with too many values, the plotting area becomes too small to print the plot in plotting panel of RStudio.
When it happens, you can try to manually increase the size of the plotting panel in your RStudio interface. If doing this doesn't solve the error, then it is advised to define a legend with fewer values for colors and/or shapes.
Warning message:
In grid.Call(C_convert, x, as.integer(whatfrom), as.integer(whatto), :
reached elapsed time limit.
This warning seems to happen randomly when executing code using the ggplot2 and/or grid packages. Usually after executing one more time the chunck of code the warning does not display anymore. The current statues of this issue can be tracked here.
Warning message:
Using alpha for a discrete variable is not advised. This warning can arise when using the function ggvolcano.corr() with additionnal ggplot2 components. It doesn't compromise the printing of the plot, however you might feel annoyed by it.
A quick fix to suppress specifically this warning is to use the function warn.handle(), which filters out annoying warnings using pattern matching, as following:
#Create your correlation volcano plot (this will also print the 'default' volcano plot)
my_volcano <- ggvolcano.corr(
data = dfrm_my_correlation_res, p.cutoff = 0.01, corr.cutoff = 0.1,
title.corr.cutoff = "Samples default correlation",
corr.label.cutoff = c(-0.35,0.40)) +
scale_color_manual(values = ggsci::pal_npg("nrc", alpha = 1)(10)) +
xlab("Spearman correlation") + ylab("Spearman P-value") +
ggtitle("Spearman correlation between multiple variables and my variable of interest")
#Print your volcano plot without displaying the annoying warning
warn.handle(
pattern = "Using alpha for a discrete variable is not advised.",
print(my_volcano)) Nevertheless, using ggvolcano.corr() without additionnal ggplot2 components
should not raise this warning.
Warning message:
ggrepel: ## unlabeled data points (too many overlaps). Consider increasing max.overlapsThis warning can arise when using the function ggbipca(). If the scale is too small, and you want to display too many loadings labels, then those overlapping will not be displayed, and this warning will be printed. Using this function has shown that this specific warning can persist, and be printed randomly afterward when running other commands. It is unclear why this is happening. But it can be fixed by executing the following command, once you ran ggbipca():
assign("last.warning", NULL, envir = baseenv())The current statues of this issue can be tracked here.
Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -InfThis warning can arise when using the function sunset()when there is only 1 label displayed on the right Y axis. This warning does not compromise the result and should be ignored.
The current statues of this issue can be tracked here.
