issue in chromosome name

I've tried the following with this karyotype file:

devtools::install_github('TickingClock1992/RIdeogram')

require(RIdeogram)

setwd('/home/juan/Desktop/juan/bio/svevo-zavitan')
data(human_karyotype, package="RIdeogram")
data(gene_density, package="RIdeogram")

human_karyotype
gene_density

karyo = read.csv(file="data/karyotype.csv", header=TRUE, sep=",")
density = read.csv(file="data/snp_dens.csv", header=TRUE, sep=",")

ideogram(karyotype = karyo, overlaid = density)
convertSVG("chromosome.svg", device = "png")


Chr,Start,End,CE_start,CE_end
chr1A,0,585266722,0,0
chr1B,0,681112512,0,0
chr2A,0,775448786,0,0
chr2B,0,790338525,0,0
chr3A,0,746673839,0,0
chr3B,0,836514780,0,0
chr4A,0,736872137,0,0
chr4B,0,676292951,0,0
chr5A,0,669155517,0,0
chr5B,0,701372996,0,0
chr6A,0,615672275,0,0
chr6B,0,698614761,0,0
chr7A,0,728031845,0,0
chr7B,0,722970987,0,0
chrUn,0,498719471,0,0

and got the following error:

ideogram(karyotype = karyo, overlaid = density) Error in nchar(karyotype$Chr) : 'nchar()' requires a character vector

So I have to modify my karyotype as follow:

Chr,Start,End,CE_start,CE_end
1,0,585266722,0,0
2,0,681112512,0,0
3,0,775448786,0,0
4,0,790338525,0,0
5,0,746673839,0,0
6,0,836514780,0,0
7,0,736872137,0,0
8,0,676292951,0,0
9,0,669155517,0,0
10,0,701372996,0,0
11,0,615672275,0,0
12,0,698614761,0,0
13,0,728031845,0,0
14,0,722970987,0,0
15,0,498719471,0,0

Would be nice to support the other format
