Dear Jim, Thank you very much for the help. The code seems to be right. Using this code, I got exactly the same value as the excel's value. This is great. Thanks MW On Wed, Dec 22, 2021 at 10:57 PM jim holtman wrote: > You need to use the 'ifelse' function. I think I copied down your > formula

Re: [R] able to estimate in the excel but not in R, any suggestion?

You need to use the 'ifelse' function. I think I copied down your formula and here is the output: > daT<-structure(list(sd = c(0.481, 0.682, 0.741, 0.394, 0.2, 0.655, 0.375), + mcd = c(51.305, 51.284, 51.249, 51.2, 51.137, 51.059, 50.968), ca = + c(49.313, 69.985, 75.914, 40.303, 20.493,

[R] able to estimate in the excel but not in R, any suggestion?

Hi R users, I was trying to estimate some values in r but could not figure out how to write the script in r. Although I was able to estimate it correctly in the excel. For example I have the following data set. daT<-structure(list(sd = c(0.481, 0.682, 0.741, 0.394, 0.2, 0.655, 0.375), mcd =

Re: [R] Speed up studentized confidence intervals ?

I’m wondering if this is an X-Y problem. (A request to do X when the real problem should be doing Y. ) You haven’t explained the goals in natural or mathematical language which is leaving me to wonder why you are doing either sampling or replication (much less doing both within each iteration

Stephen, Why should there be a column header when you take your data and reformat it? cat(format(v1, justify = "right"), sep = "\n") The above is no longer your original data structure and has specified what you want printed. Your column header and other names associated with your original

Hello, The problem is that the vectors of unique values in each column of the original data.frame Data need not be same length. And the output of sort(unique(.)) is a list of vectors of different lengths. And lists print "horizontally", each vector on its own. Like Duncan said, one of the

Bert, Thanks for the reply. I did not think to put values back into the same column. This action would not make sense to me, as it would destroy data integrity. I guess adding to a new column in the same container, in this case a dataframe, is possible but again not probable with me.
