Hello list,

Thanks in advance for any help.

I have many (approx 20) files that I have merged.  For example

d1<-read.csv("AlleleReport.csv")
d2<-read.csv("AlleleReport.csv")

m1 <- merge(d1, d2,  by = c("IND", intersect(colnames(d1), colnames(d2))),
all = TRUE)
m2 <- merge(m1, d3,  by = c("IND", intersect(colnames(m1), colnames(d3))),
all = TRUE)
