Hi,
I have two tables and I need to merge both. I use the merge command, but
in this way the name must be exactly. How I can make to compare
independently of upper or lower-case?
Look:
data1<-data.frame(journal=c("Ecology","Environmental
Entomology","Neotropical Biology And Conservation"))
data2<-data.frame(journal=c("Ecology","Environmental
Entomology","Neotropical Biology and
Conservation","Sociobiology"),qualis=c("A1","A2","B1","B5"))
merge(data1,data2)
> merge(data1,data2)
journal qualis
1 Ecology A1
2 Environmental Entomology A2
the expected result is:
journal qualis
1 Ecology A1
2 Environmental Entomology A2
3 Neotropical Biology And Conservation B1
Look that result is wrong because the "And" and "and" in the name
"Neotropical Biology And Conservation"
how to fix it automatically? Has any function to make all names
lowercase or any other mean to make this to work.
Thanks
Ronaldo
