[R] Different Estimated values between R and Excel

[Komine]

Hi,
I used simple linear regression with the R software and EXCEL on the same
data. Although , I find the same R2=0.84, I find different estimated values
(intercept and slope). For the R software (slope =0.0009, Intercept =
-0.1478), for EXCEL (slope =927.7, Intercept = 154,41).   
When I use the estimated values from the R software, the results seem bad,
however the results of Exel seem correct. 
Do you know why I have different estimated values between the R software and
EXCEL?
I give below a sample of data:
Thank you in advance 

var1	var2
0,11	264,6
0,01	226,7
0,05	168,1
-0,03	144,9
-0,07	108,1
0	118,22
-0,09	85,6
-0,07	103
-0,05	89,6
-0,06	92,8
-0,11	64,9
-0,11	33
-0,08	32,5
-0,12	42,3
-0,14	36,7
