用rpy2将R对象转换为Python对象

correlation = robjects.r(\'function(x, y) cor.test(x, y)\')
corr= correlation(robjects.IntVector(goodtotemp), robjects.IntVector(goodGDPs))
print corr

print corr[3]
print \'coef:\',type(corr[3])

     cor 
0.984881 
coef: <class \'rpy2.robjects.vectors.FloatVector\'>

c=corr[3]
print \'c:\',c*10., type(c)

c:
Traceback (most recent call last):

    print \'c:\',c*10., type(c)
TypeError: unsupported operand type(s) for *: \'FloatVector\' and \'float\'
