Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error. The message is: Error in

hi there, i an beginner of R. some one have sent me a file (extension is .Rdata). i have installed R in my computer and i just double clicked the data. then it automatically opened R programme and displayed that [previously saved workspace restored]. the following message was displayed. Type 'demo()' for some demos, 'help()' for on-line help, or'help.start()' for an

Actually, sorry, my fix was for the case where you had other arguments beginning with @ that weren't response files, whereas yours has actual response files, so my patch won't help there.

Hi, I recently hit this on a project using a build system that relies heavily on nested response files. We found we could only have 21 response files total before getting errors related to the unexpanded response files. I tracked it down to this code in llvm/lib/Support/CommandLine.cpp // If we have too many response files, leave some unexpanded. This avoids // crashing on

Hi R user, Would you mind to help me to find the range with stochastic events? For example, daT<-structure(list(sn = 1:14, growthrate = c(0.5, 0.6, 0.7, 0.99, 0.1, 0.3, 0.4, 0.5, 0.5, 0.2, 0.1, 0.4, 0.3, 0.43)), .Names = c("sn", "growthrate"), class = "data.frame", row.names = c(NA, -14L)) I want to find the ranges of growth rate of the above data using Mote

Hi R User, Would you give me your hand to standardize some columns in a matrix?

Hello, I have been following the STI example in AWDWR and have a question about presenting the output. I want to output a list of Person objects that are grouped by their type. I have an array of all the Person objects and I would like the output to be as follows. Employee x3 <ul> <li>Employee 1</li> <li>Employee 2</li> <li>Employee 3</li> </ul>

Hi R experts, Could you please help me to fit a linear, cubic and quadratic curve in a figure? I was trying to show all these three fitting curves with different colour in one figure. I spent substantial time to figure it out, but I could not. I have given here a example and what I did for linear, but no idea for cubic and quadratic fitting curve > dput(test) structure(list(sp = c(4L, 5L,

Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think. I have very big data but I have created a hypothetical data for simplification. for example I have : table 1 table 1: species occurance data

Hello, I have set up that uses single table inheritance. I have a number of model subclasses following the example in AWDWR that uses Manager < Employee < Person. First question. Do I need to create controller classes for each? I don''t think I do because a single controller should be able to shunt the data between the models and the views. Second question. Say I have a view

Hi R- User I have very big data set (5000 rows). I wanted to make classes based on a column of that table (that column has the data which is continuous .) After converting into different class, this class would be Unique ID. I want to run regression for each ID. For example I have a data set > dput(dat) structure(list(ID = c(0.1, 0.8, 0.1, 1.5, 1.1, 0.9, 1.8, 2.5, 2, 2.5, 2.8, 3, 3.1, 3.2,

Hello, I am new to R and I am attempting to use the ProbForecastGOP package for some research I am conducting. The package works fine when I call the functions from the command line as the examples instruct. However, I am attempting to step through some of the functions so that I can obtain a better idea of what is going on. I have come to the following command:

Hi R User, I calculated a correlation matrix and I was trying to give a same name for rows and columns (heading) in the correlation matrix. But, I was not able to do so.
