[R] Extracting output data into a vector or matrix

I've been struggling to do the following:   After a lengthy computation, I receive an output along the lines of the list below.   This list has 41 values and is not the end of my computations. I have another computation to do on the list below, but in this final computation the list is supposed to be a vector.   I've tried to assign the list below to a data frame and then extract it, but not luck! Cleary, this is because each of the outputs in the list represents an individual data point that is not regarded as part of a matrix. Any help? I desperately need to be able to extract all the output data into a Vector so I can perform the final step of my computation.   The final step is:    

  fn<-(R*(R1R-R10R)) + (R*((KR/VR)-(p[1]/p[2])))* ifint    

  Thanks in advance.        

  ifint<-integrate(f,0,40,w=w$t,y=w$fint.i.)$val   ifint
