Error for single base plotting

[kaufm202]

I am attempting to plot a single base to represent overall nucleotide frequency is a group of sequences. I already have the program setup to get the frequency values into a matrix as shown below:

test
[,1]
A 9765608
C 6271383
G 5865611
U 12051811

When I attempt to plot this, I get this error:

ggseqlogo(test, method='p', ncol=1, seq_type="rna")
Error in apply(pwm, 2, function(col) sum(col * log2(col), na.rm = T)) :
dim(X) must have a positive length

It seems to be an issue with the matrix only having one column, since if I add a column of arbitrary values, I am able to plot it. For example, using the matrix shown below:

test2
[,1] [,2]
A 9765608 1
C 6271383 2
G 5865611 3
U 12051811 4

Is there any way around this to be able to plot a single base from a frequency matrix? Thank you!
