R help - Oct 2013 - Why read.table replacing space with "." in the header

Hi,
Use `check.names=FALSE`
head(dd,2)
#? Phylo.Tree Genesis.Tree
#1????????? 1??????????? 2
#2????????? 2??????????? 3

?dd <- data.frame("Phylo Tree"= c(1:10), "Genesis Tree"=
c(2:11),check.names=FALSE)
head(dd,2)
#? Phylo Tree Genesis Tree
#1????????? 1??????????? 2
#2????????? 2??????????? 3
write.csv(dd,"Crish.csv",row.names=FALSE)
?yy<- read.csv("Crish.csv",header=TRUE,check.names=FALSE)
?head(yy,2)
#? Phylo Tree Genesis Tree
#1????????? 1??????????? 2
#2????????? 2??????????? 3

A.K.



Hello Guys 

Please look at the following code. I dont have "." in the input 
data frame. But why i am getting when i read the data.frame again. 

dd <- data.frame("Phylo Tree"= c(1:10), "Genesis Tree"=
c(2:11))
?write.table(dd, "D:\\Write_XML\\testdf.csv", sep=",") 
?yy <- read.table("D:\\Write_XML\\testdf.csv", sep=",") 
?names(yy) 
[1] "Phylo.Tree" ? "Genesis.Tree" 


Thanks
