similar to: New R function is.nana = is.na & !is.nan

"nana" is meant to express "NA, really NA". Your suggestion sounds good.

Happy New Year everybody! The name (is.nana) doesn't make much sense to me. Can you explain it? One alternative would be to add an extra argument (e.g. 'strict') to is.na(). FALSE by default, and ignored (with or w/o a warning) when the type of 'x' is not "numeric". H. On 12/31/19 22:16, Jan Gorecki wrote: > Hello R-devel, > > Best wishes in the new

Dear R developers, I spotted that R_isNA and R_IsNaN could be improved when applied on a vector where we could take out small part of their logic, run it once, and then reuse inside the loop. I setup tiny plain-C experiment. Taking R_IsNA, R_IsNaN from R's arithmetic.c, and building R_vIsNA and R_vIsNaN accordingly. For double input of size 1e9 (having some NA and NaN) I observed following

Hi, FWIW: /* Taken from R/src/main/unique.c */ static int requal(SEXP x, int i, SEXP y, int j) { if (i < 0 || j < 0) return 0; if (!ISNAN(REAL(x)[i]) && !ISNAN(REAL(y)[j])) return (REAL(x)[i] == REAL(y)[j]); else if (R_IsNA(REAL(x)[i]) && R_IsNA(REAL(y)[j])) return 1; else if (R_IsNaN(REAL(x)[i]) && R_IsNaN(REAL(y)[j])) return 1;

Hello, I was trying to install Rggobi in the latest version of R and it gave me a compilation error for R CMD INSTALL Rggobi_1.0-0.tar.gz RSGGobi.C: In function RS_GGOBI_init (R_IsNaNorNA) undeclared (line 77) I searched for this function in R src files and it was abandoned in ~/R-2.0.0/src/include/R_ext/Arith.h file. Only functions int R_IsNA(double); /* True for R's NA only */

R-2.9.0/include/R_ext/Arith.h has: int R_IsNA(double); /* True for R's NA only */ int R_IsNaN(double); /* True for special NaN, *not* for NA */ int R_finite(double); /* True if none of NA, NaN, +/-Inf */ #define ISNA(x) R_IsNA(x) /* True for *both* NA and NaN. The first and last lines are contradictory - if R_IsNA is true only for NA, not NaN, then ISNA should be the same.

Hi R-devel, I have a question about the differentiation between NA and NaN values as implemented in R. In arithmetic.c, we have int R_IsNA(double x) { if (isnan(x)) { ieee_double y; y.value = x; return (y.word[lw] == 1954); } return 0; } ieee_double is just used for type punning so we can check the final bits and see if they're equal to 1954; if they are, x is NA, if they're

Dear Jan, Looking at your examples, I just see you have hand-inlined R_IsNA/R_IsNaN, or is there anything more? In principle we could put

Hi the list, I need to write some efficient distances function, so I read the code for the Euclidean distance. I do not understand the purpose of the line 11 : if x[i] and y[i] are not NA (line 9), can dev be NA ?

In the hope of some meaningful response and ignoring the risk of further abuse, let me try to clarify the issue here. I have re-read the 'Writing R Extensions' manual. It seems to me that it clearly says R API functions can be called from from C++ programs, and the API includes the special values ISNAN() and R_FINITE() and the missing test ISNA(). R_FINITE is no problem. It is

Hi All, I have conducted the following survival analysis which appears to be OK (thanks BRipley for solving my earlier problem). > surv.mod1 <- survreg( Surv(timep1, relall6)~randgrpc, data=Dataset, dist="weibull", scale = 1) > summary(surv.mod1) Call: survreg(formula = Surv(timep1, relall6) ~ randgrpc, data = Dataset, dist = "weibull", scale = 1)

Dear CSAG R users, I will be glad if someone can point out what I am doing wrong or not doing at all in this. I am trying to write out netcdf file in R. I have 26 time step but only the first time step is written. For example: >library(ncdf) >path <- '/home/work/' >forecast <- open.ncdf(paste(path,'cam.1980.2005.nc',sep="")) > fore <-

Hi All, I am currently conducting a mixed model. I have 7 repeated measures on a simulated clinical trial. If I understand the model correctly, the outcome is the measure (as a factor) the predictors are clinical group and trial (1-7). The fixed factors are the measure and group. The random factors are the intercept and id and group. I tried using 2 functions to calculate mixed effects.

Hello, I have a samba PDC with an openLDAP backend. on my windows 7 machines which have joined the Samba PDC domain I cannot see the groups on windows. Does anyone know the reason why ?

Hi I am sure that this question has been asked before ... appologies in advance This - which comes out very nicely - better than the commercial stuff. plotmeans (cdpy~Dodefordpy, Data = Dataset, connect = False, minbar = 1, mean.labels = FALSE, col = "blue", barwidth = 1.5, barcol = "red", ci.label = FALSE, xlab="Onset", pch = 15, par(las =2)).

Hi All., Following on from all the help I received earlier .. Just so as you know a well known text book (T&F) uses "repeated observations" - I think perhaps they meant repeated measures in retrospect I am a total beginer to ARIMA, but have read a a basic text. I read that ARIMA requires a minimum of 50 repeated measures in time (repeated measures)- Unfortunately, I have 8

Hi everyone, I made this set of boxplots that would show me the widths of some sites broken up by some chromosome, but I don't know how to make it indicate the number of data points that created the boxplot. How do I do that? boxplot(data$site~data$chr,varwidth='TRUE') -- View this message in context: http://r.789695.n4.nabble.com/boxplot-width-tp2266805p2266805.html Sent from the
