[R] NAs introduced by coercion

Hi, In glmnet, while using a matrix as an input, I get an error of NA's introduced by coercion. However in the input there is no NA value. cvfit = cv.glmnet( x = mat1, y = train$response,family="multinomial", type.multinomial = "grouped", parallel = TRUE) Error in lognet(x, is.sparse, ix, jx,

Yes, you can use the knitr package directly (that is what Rstudio uses, but it is its own package). On Fri, Jan 8, 2016 at 1:16 PM, Ragia . wrote: > dear group, > is there a way to write my outputs to any kind of files ( the output contains > text and graph) using R only

There was a mistake in the previously sent function. I had hard coded the values of parameters `nu' and `exi'. Use this one: myroot <- function(t, nu, exi, alpha){ fun <- function(t, exi, nu) (nu+t^2)^(-(nu+1)/2)*exp(((nu+1)*exi*t)/((nu+t^2)^0.5)) res <- alpha - integrate(fun, -Inf, t,

Re: [R] plot 2D matrix of RGB values

There is ?rasterImage which can take a matrix of hex values, or a 3D array of individual colour dimension values in RGB. It's pretty low-level, used to add to an existing plot. The ancient ?image function leverages this facility if you use "useRaster = TRUE". The "raster" package (no relation),
