search for: offsprings

Hi all, I am reading a huge data set(12M rows) that contains family information, Offspring, Parent1 and Parent2 Parent1 and parent2 should be in the first column as an offspring before their offspring information. Their parent information (parent1 and parent2) should be set to zero, if unknown. Also the first column should be unique. Here is my sample data set and desired output. fam

Sorry that I was unclear. For an individual to qualify for my analysis I want both of the following two criteria to be fulfilled: First, I want to select measurement taken at a certain age: for the focal individual the year of measurement (year) should be the same as year.hatch Second, I want the focal individual to be born by a mother that reproduces for the first time. So the /parents /of

Hi people, I'd like to understand valid users and file permissions better. I have a share which is not behaving as I expect. [family] path = /home/shares/family create mask = 0664 directory mask = 0775 force group = parental guest ok = No valid users = @parental, @family writeable = Yes in Group parental are mum & dad; in group family are mum, dad and offspring. With file permissions

Dear Rlers, in the following dataset I would like to insert a new column that refers to the data of the previous row. My question is whether the probability of a female (Id) changes if she had given birth to a pup in the previous year. So my dataframe consists of the column Id, year (2003-2007 for each Id) and offspring (=of; 1-0): Id year of 1 2003 1 1 2004 0 1

Dear R users, I encounter a problem regarding number of significant digits on y-axis. Below is my basic code: myplotkid<-xyplot(expected_offspringnumber~afr|decade,groups=SES,data1, auto.key=list(space="right"),layout=c(9,1),xlab="",ylab="Offspring number", aspect="fill",scales=list(x=list(draw=F)),strip=T) >From this code, you can see there are 9

Hi, I recently noticed that a relativly short wav file loses the last second (truncated perhaps) when I ran it through oggenc. Originally the wav was 25 seconds, the ogg is 24 seconds. This happens at various quality levels, and I saved several copys of the file on a webserver at http://array26.rockefeller.edu/www/ogg/ If anyone wants to confirm my observations. The command lines were:

I am getting "Chi-squared approximation may be incorrect in: chisq.test(x)" with the data bleow. Frequency distribution of number of male offspring in families of size 5. Number of Male Offspring N 0 518 1 2245 2 4621 3 4753 4 2476 5

Is there a way I can have R automatically execute the commands in a source file without ever having to use R interactively? If so, what arguments should I pass to the UNIX call to R? I need to do this to run several R jobs in parallel. An alternative may be to have R and an R package behave as a stand-alone application that can be called from the UNIX command line. Is there any documentation on

R-Users, Hopefully someone can shed some light on these questions as I had little luck searching the archives (although I probably missed something in my search due to the search phrase). I estimated multinomial probabilities for some count data (number successful offspring) ranging from 0 to 8 (9 possible response categories). I constructed a barplot (using barplot2) and I want to

Hi, I am sampling two random columns from females and two random columns from males to produce tetraploid offspring. For every female I am sampling a random male. In the end I want to write out a a matrix with all the offspring, but that does not work. I get always only the offspring from the last females. There must be a mistake in my script: moms<-read.delim("females.txt",

Hi, I am trying to fit a curve to data. My command line is: model10=nls(offspring~((A*c^k)/gamma(k))*((degdays-alpha)^(k-1))*exp(-c*(degdays-alpha)), start=list(A=30,k=2,c=.018,alpha=131)) I get the error message: Error in numericDeriv(form[[3]], names(ind), env) : Missing value or an infinity produced when evaluating the model In addition: Warning message: full precision was not

Hi all, I wonder if anyone can help, I have a dataframe with columns for... 'I.D' 'age' 'mothers I.D' 01 5 03 02 6 06 03 16 NA 04 8 06 05 3 NA 06 17 NA I need to create a new column for 'mothers age' which puts the age of the individual with 'mothers i.d' into the row for her offspring (so

Hi All, I'd like to ask for a few clarifications. I am doing some calculations over some biggish datasets. One has ~ 23000 rows, and 6 columns, the other has ~620000 rows and 6 columns. I am using these datasets to perform a simulation of of haplotype coalescence over a pedigree (the datestes themselves are pedigree information). I created a new dataset (same number of rows as the pedigree

...details: The data is animal science data in which five sires were randomly sampled from the population and were randomly mated with two dams. Two offspring per sire dam combination were measured. Average daily gain was recorded. We are interested in breeding value of ith sire(means that which gives offsprings with higher gain NIL [[alternative HTML version deleted]]

A student asked me about simulation he is doing. This simulation presented an interesting R programming puzzle that we did solve but I am not happy with the solution. I feel there should be a better way of doing this. Briefly, he is simulating births and deaths in a linear array of cells. Births and deaths are required to alternate. For a birth, one of the cells is selected at random to be the

Hi all, I try to generate sets of strategies that contain probability distributions for a defined number of elements, e.g. imagine an animal that can produce 5 different types of offspring and I want to figure out which percentage of each type it should produce in order to maximize its fitness. In order to do so, I need to calculate the fitness for all potential strategies. As an example, if I

Dear R users, I encounter a problem regarding space control in xyplot. Basically, I want to control spaces between label, tick and axis. I remember there is a function called mgp in general plot. Is there a similar function for xyplot or xYplot? Below is my basic code: myplotkid<-xyplot(expected_offspringnumber~afr|decade,groups=SES,data1,

Hi, I have a dataframe that contains pedigree information; that is individual, sire and dam identities as separate columns. It also has date of birth. These identifiers are not numeric, or not sequential. Obviously, an identifier can appear in one or two columns, depending on whether it was a parent or not. These should be consistent. Not all identifiers appear in the individual column - it is

Hi All, is there any chance of vectorising the two ifelse() statements in the following code: for(i in gp){ new[i,1] = ifelse(srow[i]>0, new[srow[i],zippo[i]], sample(1:100, 1, prob =Y1, rep = T)) new[i,2] = ifelse(drow[i]>0, new[drow[i]>0,zappo[i]], sample(1:100, 1, prob =Y1, rep = T)) } Where I am forced to check if the value of drow and srow are >0 for each line... in

...uot;matrix population models" and Rmetasim package,but I find it's very difficult to understand this model fully and can't find a good teacher.My question is that:Now I do some research about one marine shrimp: Penaeus chinensis, it's life cycle is one year. after it breed it's offsprings, it will died. This shrimp's life cycle is dicrete ,if i use project matrix or life cyle graph to express it,how can i do it? Best regards luan_sheng
