    Fitting distribution in R

    Use fitdistr in MASS package

    Example;

    fitdistr(as.vector(res.score.m), densefun = 'normal')

    Differences between do.call and lapply
    Consider this. If L is a list with n components then

    – do.call(f, L) calls f once
    – lapply(L, f) calls f n times

    list to matrix in R

    matrix(unlist(list.data), nrow=num.row, byrow=TRUE)

    To convert list of list to matrix,

    do.call(rbind, sapply(list.data, unlist))

    Getting names while applying sapply or lapply in R.
    sapply or lapply extract the element without the row name.
    So this code does not work.

    par(mfrow = c(4,4))
sapply(names(score.avg)
       , function(x) {
           plot(x
                , type = 'l'
              );
           title(main=names(x))      
           })

    In order to use the row names while applying sapply or apply,
    pass the names of the list to a function and call the values using the names.

    par(mfrow = c(4,4))
sapply( recherche personne nom jeune fille names(score.avg)
       , function(x) {
           xlength <- length(score.avg[[x]]);         
           plot(-499:(xlength-499-1),  ce contenu score.avg[[x]]
                , type = 'l'
                , xlab='Distance from TSS', ylab='score'
             #   , xlim=c(-100,100)
              );
           title(main=x, cex.main=0.85);
           })

    The cross-reference and Track Changes do not get along well. I figured out that the numbering may not be correct/updated till accept/reject all changes. If you want to keep the previous changes, you are in trouble. Track Changes seems to be meant to track changes ‘once’.

    What is Track Changes in Word?

    If you want to keep track the history of the changes, this plugin may help.

    p.s. The numbering and formatting of the citations does not seem to work correctly. I just don’t have a gut to touch my proposal to figure out what is wrong. It will be easier to go back to LaTeX.
