Printing multi-line R output from PHP

Question

I am using venn() of gplots package of R and I want to print the intersections on php. I am executing R using exec() and printing the output, it only prints last lines of a.

library(gplots)
f <- list(a, b, c, d, e)

info<-venn(f)
aa<-attr(info, "intersections")
print(aa)

Answer 1

Take individual intersections and merge them in a single variable. You can try like this.

library(gplots)
f <- list(a, b, c, d, e)

info<-venn(f)
a<-attr(info, "intersections")$`A:B:C:D`
aa<-attr(info, "intersections")$`A:B:C:E`
aaa<-attr(info, "intersections")$`A:B:C:D:E`
a<-toString(paste(a,collapse=","))
aa<-toString(paste(aa,collapse=","))
aaa<-toString(paste(aaa,collapse=","))
x<-paste(a,aa,aaa,sep = "|")
print(x)
