Seems to work fine on my machine:
> data1 <- read.table("http://www.talgalili.com/files/aa.txt",
+ header = TRUE, sep = "\t", encoding="UTF-8", check.names=FALSE)
> data1
אחת שתיים שלוש
1 12 97 6
2 123 354 44
3 6 1 3
> colnames(data1)
[1] "אחת" "שתיים" "שלוש"
> colnames(data1)[1]
[1] "אחת"
> strsplit(colnames(data1)[1], "")[[1]][1]
[1] "א"
> data1[,"שתיים"]
[1] 97 354 1
> lm(`שתיים` ~ `שלוש`, data=data1)
Call:
lm(formula = שתיים ~ שלוש, data = data1)
Coefficients:
(Intercept) שלוש
