Hi:
Can anyone advice me on how to loop and perform a
calculation through all the columns.
here's my data
xd<-
c(2.2024,2.4216,1.4672,1.4817,1.4957,1.4431,1.5676)
pd<-
c(0.017046,0.018504,0.012157,0.012253,0.012348,0.011997,0.012825)
td<- c(160524,163565,143973,111956,89677,95269,81558)
mydf<-data.frame(xd,pd,td)
trans<-t(mydf)
trans
I have these values that I need to include while
looping:
varA<- 0.0000036084
covAB<- (-0.0000013046)
varB<- 0.00000052628
After transposing my dataframe I need something like
the following:
varA + col1*covAB + col2*covAB + col1*col2*varB
varA + col1*covAB + col3*covAB + col1*col3*varB
varA + col1*covAB + col4*covAB + col1*col4*varB
varA + col1*covAB + col5*covAB + col1*col5*varB
and so on..
then do it all over again but starting with col2
varA + col2*covAB + col3*covAB + col2*col3*varB
varA + col2*covAB + col4*covAB + col2*col4*varB
varA + col2*covAB + col5*covAB + col2*col5*varB
then col3
then col4 to col7
This is easy to do in Excel but I wonder if there's
a way to do it with R
This is the dataframe I get while doing a loop with
Excel(the values generated could bedifferent).Thanks
