...n, a logical value set to T if it's alive, some parameters for growth, diameter, etc. The tree list has another list in it which is a new data type for me. I want to make a new list that retains all the live trees. That is where Living == T. Here's the summary of the list: > summary(tf) Length Class Mode id 10 -none- numeric x 10 -none- numeric y 10 -none- numeric A 10 -none- numeric NegB 10 -none- numeric K 10 -none- numeric Age 10 -none- numeric DBH 10 -none- numeric Living 10 -none- logical pSeed 1...

Hello, What is the best way of solving this problem? answer <- ifelse(tf=TRUE, i * 5, previous answer) where as an initial condition tf[1] <- TRUE For example if, tf <- c(T,F,F,F,T,T,F) over i = 1 to 7 then the output of the function will be answer = 5 5 5 5 25 30 30 Thank you. Phil,

Estimado Jesús Para Fernández En teoría es ese material, lo vi muy rápido y en la parte genética tiene cosas que biológicamente no son así, hay un libro de Falconer, Introducción a la genética cuantitativa, que tiene escrita la parte matemática, hay un abismo entre la biología y los ingenieros que se inspiran en la biología.

If, however, I factorise the groups (in order to do e.g. anova analysis) and then plot the data test$tF=factor(test$t) plot(test$l~test$tF) abline(lm(test$l~test$tF)) the abline is now shifted up and to the left of where I would expect the line to go (through the centre of the points of each of the groups). If there is a simple explanation, could someone tell me it? ------------------------...

According to the Assembly language reference: "In LLVM, opaque types can eventually be resolved to any type (not just a structure type)." But the only way I can think of to do so is to give it a type name, then later redeclare the name. But that gives an error: %TO = type opaque %TF = type i32 ( %TO* ) %TO = type %TF gives: $ llvm-as types1.ll llvm-as: types1.ll:3:1: error: redefinition of type %TO = type %TF ^ Also, what is the set of things that can be done with an as-yet unresolved opaque type? -- Rodney Bates rodney.m.bates at acm.org

Hola, Acabo de calcular tf-idf y me surge una duda. ¿Habría un valor de idf o tf-idf que se considerara como umbral para establecer que una palabra es muy común o no?

Hi, I'm writing a function that needs the input names (as characterstrings) as part of the output. With deparse(substitute( ) ) that works fine, until I replace all zeros with 0.001 (log is calculated at some time): tf <- function(input) { input[input==0] <- 0.001 ; deparse(substitute(input)) } myguess <- 42 tf(myguess) # not "myguess", but "42" Now when I extract the input names before replacing the zeros, this works: tf <- function(input) { out <- deparse(substitute(i...

This is a not too old R-devel on Linux, it already fails in R 3.4.4, and on macOS as well. The tar file seems valid, external tar can untar it, so maybe an untar() bug. setwd(tempdir()) dir.create("pkg") cat("foobar\n", file = file.path("pkg", "NAMESPACE")) cat("this: that\n", file = file.path("pkg", "DESCRIPTION"))

Another solution is to only save the parts of the model object that interest you. As long as they don't include the formula (which is what drags along the environment it was created in), you will save space. E.g., tfun2 <- function(subset) { junk <- 1:1e6 list(subset=subset, lm(Sepal.Length ~ Sepal.Width, data=iris, subset=subset)$coef) } saveSize(tfun2(1:4)) #[1] 152 Bill Dunlap TIBCO Software wdunlap tibco.com On Wed, Jul 27, 2016 at 11:19 AM, William Dunlap <wdunlap at tibco.com> wrote...
