Hello Everyone,   This is my first attempt to do something in R. As a precursor to a Willingness to Pay analysis, I want to conduct a Mixed Conditional Logit analysis but am unsure how to proceed because of some nesting within my data.   Below is some data and code that illustrate what I’m trying to do. The data are based on responses to a conjoint survey obtained during pilot testing. In the

Hi there, I'm trying to solve 2 nonlinear equations in 2 unknowns using the BB package. The first part of my program solves 3 ODEs using the deSolve package. This part works. The output is used as parameter values in the functions I need to solve. The second part is to solve 2 equations in 2 unknowns. This does not work. I get the error message "unexpected end of input". So what

Anyone know how to let asterisk deal with the progress codes coming from the carrier? The problem I am having is when a customer calls an invalid number the carrier tells me the call is invalid via a progress code but doesn't route me to a recording (this number is invalid). Instead they hang up on me causing a fast busy or sometimes hold up the call with dead air for 15 to 30 seconds then a

Hei, i am trying to plot the means of two variables (d13C and d15N), by 2 grouping factors (Species and Year) that i obtained by the function tapply. I would like to plot with different colours according to the Year and show the "Species" as data labels. My data looks like this: Species d13C d13N Year "Species1" 14,4 11.5 2009 "Species2"

# I need to create an xyplot() where I control the specific order of # both my conditioning variables. The default code below plots the # data correctly (dispersed across all 14 columns), but fails in two # ways. Both the primary conditioning variable (Transect), and the # secondary conditioning variable (Offset) are in alphanumeric order, # rather than the specific order I need. # Here

Due to an error on my part, I have renamed the previously attached file from T_5-04b_LTC-SE-SO-Compared.csv to T_5-04b_LTC-SE-SO-Compared.txt. It remains a comma-delimited file so the extension can be changed and used per the script, or loaded separately.

Readers, For a 12 hour time stamp: > testtime<-("2013-01-01 01:00:01 PM") > testtime [1] "2013-01-01 01:00:01 PM" > testtime24hour<-strftime(testtime,'%H:%M:%S') > testtime24hour [1] "01:00:01" how to convert to 24 hour format so that the object 'testtime24hour' is: '13:00:01' Thanks. -- r2151

Readers, Previous questions about this requirement have been for m$ users, my failure occurs using linux. I have tried to add the delta (?) symbol to the y axis label and the result is &D, using the command: ...ylab="?t"... Any advice please? rhelp at conference.jabber.org mandriva 2008 r 251 (27-06-07)

I have a problem where I have two columns of data that I can simply plot using: plot(wV[0:15,3],wY[0:15,3]). This produces my desired plot. Now, say I have a third variable that I would like to introduce and use that variable to set different colors in the plot In this case, say I wanted values greater than 0 to be "blue" and values less than 0 to be "red" Basically, my

Readers, For this data set: testvalues<-c(10,20,30,40) How to amend the plot instruction: plot(testvalues,ann=FALSE,type='l',yaxt='n',xaxt='n') so that x axis ticks labels can be added to existing graph with arbitrary value such as 0,100,200,300)? Thanks in advance. -- r2151

Readers, I have data with different time stamps that I wish to plot (for example): data set 1 time(hh:mm:ss),datum 01:00:00,500 01:00:15,600 01:00:30,750 01:00:45,720 01:01:00,700 01:01:15,725 01:01:30,640 01:01:45,710 data set 2 time,datum 01:00:12,20 01:01:01,55 01:01:55,22 The time interval in data set 1 does not change, but the time interval in data set 2 does change, such that for a

Dear R help folks, First my apologizes for sending several related questions to the list server. I am trying to learn how to manipulate data in R . . . and am having difficulty getting my program to work. I greatly appreciate the help and support list member give! I am trying to write a program that will run through a data frame organized by ID and for the first line of each new group of data

Hi ,everyone. I want to draw a boxplot figure, main script shown as below. when I run the command "boxplot(bjavee~yearname)",it is wrong with the error information " model.frame.default(formula = bjavee ~ yearname) : variation 'bjavee' list is wrong". I want to add the yearname as the x-axis tick. And yearname is a array with the length 12,while bjavee is a 5*12

All, I have some data on parasites on apple leaves and want to do a goodness of fit test to a Poisson distribution. This seems to do it: mites <- c(rep(0,70), rep(1,38), rep(2,17), rep(3,10), rep(4,9), rep(5,3), rep(6,2), rep(7,1)) tab <- table(mites) NSU <- length(mites) N <-

Check out the dplyr package, specifically the mutate function. # Create new column based on existing column value df <- df %>% mutate(FirstDay = if(ID = 2, 5)) df Repeat as needed to capture all of the day/firstday combinations you want to account for. Like everything else in R, there are probably at least a dozen other ways to do this, between base R and all of the library packages

##I have 2 columns of data. The first column is unique "event IDs" that represent a phone call made to a customer. ###So, if you see 3 entries together in the first column like follows: matrix(c("call1a","call1a","call1a") ) ##then this means that this particular phone call (the first call that's logged in the data set) was transferred ##between 3
