search for: funtion

Hi, I have a variable X classified in a lot of groups and I need to run the [fitdistr] funtion for each group. I tried with the [by] or the [tapply] funtions because my data is organize in two columns (variable and the groups), but neither of these command work. If somebody have a tip to help me up I really appreciate it. thanks, [[alternative HTML version deleted]]

Have any way to write a funtion into a list ? -- Nash - morrison at ibms.sinica.edu.tw

Hi, I would like to display results on the screen . Can I use the printf function in LLVM? How do I call the funtion? Could someone give me an example Thanks Jai

...n( identical(v1,v2) ); + } > x [,1] [,2] [,3] [1,] 1 3 3 [2,] 4 5 4 [3,] 2 7 6 > apply(x, c(2), check.cols, v2=c(7,8,9)) [1] FALSE FALSE FALSE Is it possible to make the function check.cols() inline to the apply statement. Some thing like this: apply(x, c(2), funtion(v1,v2){ identical(v1,v2) }, v2=c(1,4,2)) The above gives me a syntax error. I also tried: apply(x, c(2), fun <- funtion(v1,v2){ return(identical(v1,v2)) }, v2=c(1,4,2)) and I still get a syntax error. Is this type of syntax allowed in R? Thanks, --------------------------------------------...

I'm trying to create a bargraph of means with standard error bars using the function bargraph.CI (in the sciplot package). Like this: bargraph.CI(x.factor, response,data,xlab, ylab, par(family="serif"),font=11) However, an error message comes up when I try to use the par funtion. Does the character font/style need to be changed in a different way for this kind of plot? Or am I misusing the par function? Thanks! Melissa

Hei, I just wonder the use of family=binomial in glm function. As I learned from book (e.g. Andy Field) that logistic regression (binary logit) can use glm funtion with family = binomial. Here the y is a factor variable (e.g. value = 1 or 2). But I have also seen i many other cases, same function glm with family=binomial, but y is a variable with several column , like y= cbind(y1, y2), and here y1 and y2 are the success number, failure number respectively....

Dear all, 1) I have a very large matrix of  str(keep)  num [1:153899, 1:3415] -98.6 -95.8 -96.4 -95.8 -98 ... that  I would like to reduce its size to something like str(keep)  num [1:1000, 1:3415] -98.6 -95.8 -96.4 -95.8 -98 ...  or anything similar in size as this is a matrix that needs plotting (so is ok if it is 1000 row, 995, or 1123) I think what I need here is a way of selecting

I am trying to call a funtion within another function and I clearly am misunderstanding what I should do. Below is a simple example. I know lstfun works on its own but I cannot seem to figure out how to get it to work within ukn. Basically I need to create the variable "nts". I have probably missed something simple i...

Dear R-list, Could anybody tell me (or give me a tip) of how to implement the Duncan distribution in R? I've been trying to make a new and more flexible function for multiple comparison of means: Tukey, SNK and Duncan, from 'aov' objects, like TukeyHSD function. For while, it is running nice (Tukey and SNK), for simple design (completely randomized, randomized block and Latin

Jose - Before implementing SNK and Duncan's, you may want to be aware of some criticisms of these methods: >From Hsu (1996), "Newman-Keuls multiple range test is not a confident inequalities method and cannot be recommended." "Duncan's multiple range test is not a confident inequalities method and cannot be recommended either. In the words of Tukey (1991),

  Hello, my name is German, I am from Argentina, and we are working at university with R.

Hello all! I've posted the question before but I am still struggling for an answer, please help if you can;-) Suppose a discrete series of data is generated by the following equation: CF=exp(-(t^2)/2) which is the characteristic function of a random variable X with standard normal distribution, how do I *numerically* solve for its probability density function? i.e., obtain a series of data

Dear R users, I am applying the augmented-Dickey-Fuller Unit Root Test (ur.df function of the urca package) to a time series of approximately 50 values. To be sure I understood what was going on with the ur.df function, I checked the critical values of the 3 test statistics (tau, phi2 and phi3 if a trend is included) or the 2 test statistics (tau and phi1 if only a drift is included) with the
