Hi everyone, I wonder if I can get your help using a custom function in apply. Imagine the following dataframe called "data": LowLim HighLim A1 A2 A3 A4 4 6 3 4 5 6 4 6 4 5 5 6 2 3 1 4 2 3 2 3 NA NA NA NA We have created a custom function (see below) that takes the values in a given row between columns A1 to A4 to see if they are outside the limits in the same row set by columns LowLim and HighLim, if at le...

Dear friends, I'm probably wrong but is there anything better than bootstrap to get a confidence interval of the median from a population with unspecified distribution ? Best wishes Troels Ring, Aalborg, Denmark

hello, ladyes and gentlemans. check this: means<-c(4,6,8) stand.error<-c(0.1,0.3,0.5) now i've strongly tryed to scatterplot the means(y-axis),by showing their sd with the arrow(..,code=3,angle=90) function. The problem is that my x-axis has categorical values (say, factor(x)), and the arrows() can't recognize them as right coordinates. ????? thank you all in advance B.F. insubria

...do I convert each variable from the cor.test results to a numeric data type, as it is passed into the new dataframe? For example, 'estimate', 'p.value', and 'conf.int' should be numeric not character. Second, I would like variable 'conf.int' to be two variables, 'lowlim' and 'uplim'. Many Cheers, Keith ## Create sample dataset WW_Wing_SI <- structure(list(Individual_ID = c("WW_08A_02", "WW_08A_02", "WW_08A_02", "WW_08A_02", "WW_08A_02", "WW_08A_02", "WW_08A_02", "WW_08A_02&...

...!", "Ifail=4, minpts > maxpts; should not happen!", "Ifail=5, internal non-convergence; should not happen!", ) When it finishes: Warning messages: 1: Ifail=2, lenwrk was too small. -- fix adapt() ! Check the returned relerr! in: adapt(ndim = 1 + numcycles, lower = rep(lowlim.int, (numcycles + 2: NA/Inf replaced by maximum positive value Some people already asked similar questions but couldn't find the answer. Thanks in advance Luz PS: When using the function adapt only (not within nlm) it gives no warnings.

Dear R People: I have an interactive menu via an Rcmdr extension package which asks for lower and upper limit to evaluate. Typically, I use: assign("a",as.numeric(tclvalue(lowlim)),envir=.GlobalEnv) and that's fine. However, if I try to use pi or Inf or -Inf, I get either coerced NAs or NaN. Does anyone have any suggestions, please? Thanks, Erin PS Happy Easter if you celebrate Easter. -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sc...
