Dear R user,

I want to reshape a long data frame to wide format, I made the following example files.  Can you help me?

Thank you,

Yuan Chun Ding

sample <-c("xr" , "xr" , "fh" , "fh" , "fh" , "uy" , "uy" , "uy" , "uy");
marker <-c("x" , "y" , "g" , "x" , "k" , "y" , "x" , "u" , "j");
df.long <-data.frame(sample, marker);
xr <-c(1,1,NA,NA,NA,NA);
fh <-c(1,NA,1,1,NA,NA);
uy <-c(1,1,NA,NA,1,1);

df.wide <- t(data.frame(xr,fh,uy));
colnames(df.wide)<-c("x","y","g","k", "u","j");
