Please read the "Details" section of the help file -- it essentially tells you what to do by directly using indexing; e.g. for a vector, index by: [is.na(subset) | subset] . Adjust as necessary for your data structure.Or look at the code of, e.g. subset.data.frame and create your own subset

Re: [R] question regarding the AICcmodavg package

Do not model average the regression coefficients. This makes no sense (see Cade 2015. Model averaging and muddled multimodel inferences). And, no there is no reasonable way to model average regression coefficients ala Burnham and Anderson approach when some of your models include interactions

Re: [R] question with integrate function

Hi Hanna, your function is essentially zero outside a short interval around 9. And the help page states: "If the function is approximately constant (in particular, zero) over nearly all its range it is possible that the result and error estimate may be seriously wrong." You could try to

Sorry. I meant in the previous email that the function h() is a monotone decreasing function. Thanks very much. 2018-02-06 13:32 GMT-05:00 li li : > Hi all, > The function h below is a function of c and it should be a monotone > increasing function since the integrand is

Re: [R] Question - TukeyHSD

I may be missing the point, but if you can do the calculations by hand could you not write a function in R to do the same and apply it to a data.frame of the values? On Saturday, November 4, 2017, 11:01:59 AM EDT, Paul Kent wrote: Hi, I've been

Assuming you have as your model a one-way ANOVA, you can use the aovSufficient function in HH. ## install.packages("HH") ## if you don't have it yet library(HH) ?aovSufficient On Sat, Nov 4, 2017 at 9:30 AM, Paul Kent wrote: > Hi, > > > I've been performing some

Re: [R] Question - TukeyHSD

AFAICS, without knowing the structure of your data and what specifically you wish to do, how could one answer your question? -- which is probably yes, you can do it, but without further info, ??? Maybe someone with a better crystal ball can help -- or you could clarify. Cheers, Bert Bert

Re: [R] Question on Simultaneous Equations & Forecasting

Frances, I would not advise Gauss-Seidel for non linear models. Can be quite tricky, slow and diverge. You can write your model as a non linear system of equations and use one of the nonlinear solvers. See the section "Root Finding" in the task view NumericalMathematics suggesting three

Re: [R] Question on Simultaneous Equations & Forecasting

Hi Frances, I have not touched the system.fit package for quite some time, but to solve your problem the following two pointers might be helpful: 1) Recast your model in the revised form, i.e., include your identity directly into your reaction functions, if possible. 2) For solving your model,

Sorry, I don’t think you understand my problem. dta = spark_read_csv(sc,”data_tbl”,”extension/file",delimiter = "|") dta is just a pointer to spark where the data is stored. I am using sparklyr to run this on spark. I’m not running it locally so I can’t use the $. I know how to do this locally
