I would suggest to read up a bit on the syntax  See here   if  dsnt lt 0 05      wilcox test distance result   nt   distance result   t   alternative c  two sided   paired TRUE     else if  dst lt 0 05        wilcox test distance result   nt   distance result   t   alternative c  two sided   paired TRUE    else    t test distance result   nt   distance result   t   alternative c  two sided   paired TRUE

You need to rearrange your curly brackets  Your first statement is complete  so R interprets it as such and produces syntax errors on the other lines  Your code should look like   if  dsnt lt 0 05      wilcox test distance result   nt   distance result   t   alternative c  two sided   paired TRUE    else if  dst lt 0 05      wilcox test distance result   nt   distance result   t   alternative c  two sided   paired TRUE    else     t test distance result   nt   distance result   t   alternative c  two sided   paired TRUE              To put it more simply  if you have   if condition    TRUE  x  lt - TRUE else x  lt - FALSE   Then R reads the first line and because it is complete  runs that in its entirety  When it gets to the next line  it goes  Else  Else what   because it is a completely new statement  To have R interpret the else as part of the preceding if statement  you must have curly brackets to tell R that you aren t yet finished   if condition    TRUE   x  lt - TRUE    else  x  lt - FALSE
