write.table -- maintain decimal places

Thank you for the response, Peter.  

The approach:
write.table(format(df, drop0trailing=FALSE),file='df.txt',quote=F,sep='\t',row.names=F)
surprisingly still results in some loss of trailing 0's.

df:
   EFFECT2  PVALUE
1 0.023    0.88080
2 -0.260  0.08641
3 -0.114  0.45200

df.txt:
EFFECT2    PVALUE
0.023      8.808e-01
-0.26      8.641e-02
-0.114     4.520e-01

Hello, All,

How can I maintain the decimal places when using write.table()?

Jim

e.g.

df:
   EFFECT2  PVALUE
1 0.023    0.88080
2 -0.260  0.08641
3 -0.114  0.45200

write.table(df,file='df.txt',quote=F,sep='\t',row.names=F)

write.table(format(df, drop0trailing=FALSE), ....)

Peter Ehlers

df.txt:
EFFECT2    PVALUE
0.023      0.8808
-0.26      0.08641
-0.114     0.452
