  > head(LUAD_clinicalMatrix[,c("X_EVENT","X_OS_IND")])
    X_EVENT X_OS_IND
  1      NA       NA
  2       0        0
  3       1        1
  4       0        0
  5       0        0
  6       0        0
  
  > all(LUAD_clinicalMatrix$X_EVENT==LUAD_clinicalMatrix$X_OS_UNIT)
  [1] FALSE
  
  I want to know which identifier means the sample is alive or dead, and "1" means alive or dead?
  
  user931: According to this link, 1=death 0=censor and null=no data.
