Maybe this is dumb, but I seem to be having problems reading a file saved in R v. 0.99 into R 0.90.1 (in a different machine). I did>save(test1, file="test1.RData")then I tried to read that data file in R 0.90.1:>load("test1.RData")Error in load("test1.RData") : restore file corrupted -- no data loaded More info: - both machines are running Linux; - things work the other way around (i.e., use save in 0.90.1 and load in 0.99); - things do not improve if I save as ascii; - I get the problem even with a simple vector; - (Things work, though, if I save the data frame with write.table, and then use read.table). What am I doing wrong?

Hello:
I want to ask about the accuracy of the Shapiro-Wilk's test.
I use this short program in SAS
____________________________________________________________________________
data test1;
input x @@;
cards;
1.00 1.70 2.13 2.13 2.03 2.50 2.00 2.87 2.40 2.20 1.47 1.70 1.70 1.50 1.80
1.03 0.63 0.60 1.87 1.13 1.10 1.27 0.83 0.67 1.73 2.23 2.50 1.60 1.97 2.17
2.10 0.90 0.80 2.23 0.10 0.43 0.83 0.10 0.40 0.60 1.67 1.13 1.53 1.47 0.67
0.50 1.03 1.33 1.73 1.27 0.90 1.70 2.17 0.70 0.90 0.70 1.07 0.23 0.57 0.90
0.67 1.30 1.03 0.33 0.70 1.47 1.53 1.07 0.60 0.40 0.27 1.53 1.43 2.13 0.87
1.13
;
run;
proc univariate data=test1 normal;
run;
_____________________________________________________________________________
And I obtain the following result for the Shapiro-Wilk's test
W:Normal 0.960439 Pr<W 0.0602
When I use the same data in R, with the following statement:
___________________________________________________________________________________
test1<-c(1.00,1.70,2.13,2.13,2.03,2.50,2.00,2.87,2.40,2.20,1.47,1.70,1.70,1.50,1.80,
1.03,0.63,0.60,1.87,1.13,1.10,1.27,0.83,0.67,1.73,2.23,2.50,1.60,1.97,2.17,
2.10,0.90,0.80,2.23,0.10,0.43,0.83,0.10,0.40,0.60,1.67,1.13,1.53,1.47,0.67,
0.50,1.03,1.33,1.73,1.27,0.90,1.70,2.17,0.70,0.90,0.70,1.07,0.23,0.57,0.90,
0.67,1.30,1.03,0.33,0.70,1.47,1.53,1.07,0.60,0.40,0.27,1.53,1.43,2.13,0.87,
1.13)
shapiro.test(test1)
____________________________________________________________________________________
I obtain the following answer:
Shapiro-Wilk normality test
data: test1
W = 0.9733, p-value = 0.1083
The rest of the statistics are the same, mean, median, sd, etc.
But I don't understand the difference in the Shapiro-Wilk's test of
normality.
Thank you very much for your help.

Workspaces and objects saved in earlier versions can be loaded into this version, but not conversely. Use save() or save.image() with argument oldstyle=TRUE to save in the old format if you need to. The new format is unknown to the older versions. -- Brian D.
