I need to import several ascii files in fixed format with two different record types. The data comes from European Labor Force Surveys, wich is a household survey. The first record type is for people over 16 years, and the second much sorter is for people aged 15 or less (this record has a filler with several blanks to get the same record length). The files tipically have 160000 records, with 176

Hi list, I have problems with the as.numeric function. I have imported probabilities from external data, but they are classified as factors as str() shows. Therefore my goal is to convert the colum from factor to numeric level with keeping the decimals. I have googled the problem for a while now and kept to several advices like

I have to fit a generalized linear model in R, and I have never done this before, so I'm in very much doubt. I have a dataset (of 4036 observations) claims sum grp 1 3852 34570293 1 2 1194 7776468 1 3 3916 26343305 1 4 1258 5502915 1 5 11594 711453346 1 ... there are 4 groups (grp). The task

Hi all, I have a matrix with values between 0 and 1. I want to plot this matrix on a heat map so anything >0.05 is blue, anything <=0.05 and >0.01 is yellow, and anything else is grey. I am using the heatmap.2 function. I searched around but did not find an efficient way to set colour ranges as I described. Could anybody give some hints? Thank you in advance. Wendy -- View this

Hi there, I am a beginner. I would like to change the error bars in the bargraph.CI function from the default (se) to (sd). The help file says ci.fun= function(x) c(fun(x)-se(x), fun(x)+se(x)) Is there a simple way of telling the function what (x) precisely is - I already define in in the of the bargraph.CI function and assume that is should be able to use that information. cheers, Herwig --

Greetings, I have what I hope is a simple question. I would like to change my contour interval on the vis.gam( plot.type="contour") in the mgcv package. Is this a situation where I need to modify the function or is there a default value I can change? Thanks

Hi R users: I will like to have a legend with math symbols and also with the value of a variable. But I cannot obtain both at the same time (symbol + value of a variable): Here is a reproducible example: m1<-5 m2<-12 plot(1:5,1:5,type="n") legend("topleft",legend=c(paste(expression(mu),"=",m1),expression(paste(mu,"=",m2))),lty=1:2) Thank you for

Hello Everyone, I am having problem in defining specific axis for plotting a vactor. vecAVG <- c(0.2, 0.4, 0.6, 0.2, 0.4) names(vecAVG)<-c("brain","heart","kidney","lung","blood") par(mar=c(12,4.1,4.1, 2.1))

S Programming by Venables and Ripley (2000) says on page 8, "R objects have another way to give information using the function \tttext{typeof}, which often gives the same information as \tttext{storage.mode}." It implies that there are some differences between typeof and storage.mode. However, according to ?typeof and ?storage.mode, it doesn't seem to be so. Could somebody let me

I am trying to generate predictions from a weibull survival curve but it seems that the predictions assume that the shape(scale for survfit) parameter is one(Exponential but with a strange rate estimate?). Here is an examle of the problem, the smaller the shape is the worse the discrepancy. ### Set Parameters scale<-10 shape<-.85 ### Find Mean scale*gamma(1 + 1/shape) ### Simulate Data

Hello all, I am new to R but have some experience with MATLAB and am trying to make the switch. I generally find the two languages easy to adapt but there are a few routine tasks which I would like to run smoother in R and I am having trouble finding a help resource.
