Description
Color in qbarplot does not work with boolean, or 0 containing vectors

Starter.Cell.Type.WT = c(3070 = "ExN, L4", 959 = "ExN (PCDH10)",
488 = "ExN (PCDH15)", 442 = "ExN, L2-3",191 = "ExN, L6",182 = "ExN, L5",
49 = "CR",49 = "ExN, Nascent",19 = "EPL",18 = "Astrocyte",
12 = "IPC",11 = "RG",9 = "Prog, Div.",8 = "IN, CGE",8 = "IN, Other",7 = "Prog, IN",2 = "Interferon")

## Works
qbarplot(Starter.Cell.Type.WT, plotname = "x", ylab = "Number of Cells", xlab = "xx", label = T, col = as.numeric(grepl("ExN", names(Starter.Cell.Type.WT)))+1)

## Not without +1 or grepl
as.numeric(grepl("ExN", names(Starter.Cell.Type.WT))))
grepl("ExN", names(Starter.Cell.Type.WT))
