Hi all, How does one create a matrix of values in a loop. For example, I have 46*70 matrix with columns giving the values for some blood tests performed upon the 46 patients(rows). I want to perform a simple test of normality (shapiro-wilk test) upon each of the biochemical tests for the 46 patients. Can somebody suggest the syntax for such a loop. For the data x, I wrote the following loop which

for the following example dataset:- Category Variable 1 127 1 261 1 142 1 183 1 234 1 162 2 173 2 321 2 168 2 197 2 213 2 261 3 198 3 126 3 167 3 154 3 134 3 187 3 109 3 210 I have performed Anova on the measured variable (column#2) for the groups 1,2&3 (column#1). Now I want to randomize the values in C#2 and reperform the test, say, a hundred times. Please suggest a way for this

hi all, I have a matrix with first column having some measurable values, these are indexed by the numerals 1,2 and 3 in the other columns of the data and may be interpreted as values for categories 1,2 and 3. I have written the following loop t<-1:10 for(i in 1:10) + { + k[i]<-d[(d[,(i+1)]%in%1),1] + p[i]<-d[(d[,(i+1)]%in%2),1] + t[i]<-t.test(k[i],p[i])$p.value + } Error in

Hi I'm able to create multiple plots from a dataset using a "for loop" to change variables, but when I try with stripchart it doesn't work. Standard boxplot: for(i in 2:14){boxplot(klk[,i]~Group,main=colnames(klk)[i]) Stripchart: for(i in 2:14){stripchart(klk[,i]~Group,main=colnames(klk)[i]) gives:Error in plot.window(xlim, ylim, log, asp, ...) : need finite xlim

Hi everybody, I'm a new member of the list. I'm just starting to use R. I'm looking for information about stripcharts. I didn't find a lot on the web. Outside http://www.maths.lth.se/help/R/.R/library/graphics/html/stripchart.html there isn't much I found. I'm trying to create three vertical stripcharts "glued" to one another. I succeeded to create one

I am writing course notes in LaTeX. In the part where I am describing model-fitting functions in R I want to use a ~ character inline. If I am displaying an example of R code in its own environment I use the alltt environment, which protects the ~ character. I have forgotten how to protect the ~ when I am writing something like The operator `~' is used to define a model formula in \R.
