Plotting incorrectly

cts <- c(27, 7, 17, 12, 12, 11, 5, 0, 12, 0, 1, 1, 0, 4, 0, 1, 0, 4, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1)

nms <- c("A", "B", "C", "D", "E", "F", "A&B", "A&C", "A&D", "A&E", "A&F", "B&C", "B&D", "B&E", "B&F", "C&D", "C&E", "C&F", "D&E", "D&F", "E&F", "A&B&C", "A&B&D", "A&B&E", "A&B&F", "A&C&D", "A&C&E", "A&C&F", "A&D&E", "A&D&F", "A&E&F", "B&C&D", "B&C&E", "B&C&F", "B&D&E", "B&D&F", "B&E&F", "C&D&E", "C&D&F", "C&E&F", "D&E&F", "A&B&C&D", "A&B&C&E", "A&B&C&F", "A&B&D&E", "A&B&D&F", "A&B&E&F", "A&C&D&E", "A&C&D&F", "A&C&E&F", "A&D&E&F", "B&C&D&E", "B&C&D&F", "B&C&E&F", "B&D&E&F", "C&D&E&F", "A&B&C&D&E", "A&B&C&D&F", "A&B&C&E&F", "A&B&D&E&F", "A&C&D&E&F", "B&C&D&E&F", "A&B&C&D&E&F")

venn <- structure(combs_cnt, names=combs_txt)
plot(euler(venn, shape="ellipse"), quantities=T)

For example, there should be a total of 49 in the circle for A, but this plot shows only 46. A alone, A&B, A&D, A&F and A&D&F are correct, but A&C&D, A&B&D&E and A&B&C&D&E&F are missing.

Any advice?

There is no guarantee that the resulting diagram is going to be exact (i.e. perfectly represent the input). Please make it a habit to always check the fit before plotting.

Observe that some intersections are missing, hence the missing quantities in the plot.

Thanks for the response. In case anyone lands here from Googling a similar issue, I found UpSetR a useful solution for this problem
