Dear Members

I am trying to create a venn diagram with four sets using VennDiagram 1.5.1
package. When I try to plot,it gives me the following error message

  Error in draw.quad.venn(area1 = 263, area2 = 311, area3 = 319, area4 =
293,  :
  Impossible: partial areas negative.

I call the function as mentioned below

> venn.plot <- draw.quad.venn( area1 = 263, area2 = 311, area3 = 319, area4
= 293, n12 = 230, n13 = 216, n14 = 217, n23 = 226, n24 = 214, n34 = 228,
n123 = 227, n124 = 213, n134 = 214, n234 = 250, n1234 = 212, category =
c("First", "Second", "Third", "Fourth"),fill = c("orange", "red", "green",
"blue"), lty = "dashed", cex = 2, cat.cex = 2, cat.col = c("orange", "red",
"green", "blue"));
Error in draw.quad.venn(area1 = 263, area2 = 311, area3 = 319, area4 = 293,
 :
  Impossible: partial areas negative
