Hello I have a dataset named "b2" with 1521 rows, in that dataset i have 64 rows containing specific information. the rownumbers with specific info are: + i [1] 22 53 104 127 151 196 235 238 249 250 263 335 344 353 362 370 389 422 458 459 473 492 502 530 561 624 647 651 666 671 [31] 715 784 791 807 813 823 830 841 862 865 1036 1051 1062 1068 1092 1109 1171 1187 1283 1293 1325...

Hello Rprofessionals, The SOM-Obj works very well, when i normalize my data and the plot-function, too ! But i miss or didn't find the possibility , extract the information from the SOMplot "clusterSize" and "mean" for every cluster as quantitative information ( i.e. the DataFrame with an additional column which define the calculate clusters from SOM)? My intention -

Hi, How can I avoid xtable of printing rownumbers when exporting a data.frame ? Are there more packages that deal with LaTeX besides xtable and Sweave ? Thanks EJ

Hello, I have a matrix and I want to sample 20 rows that are the the percentiles of 0-100 in 0.05 increments. I have a vector of my sequence (0, 0.05, 0.10, 0.15,....1.0) and also a normalised vector of rownumbers. That is, there are 234 rows (for example) so I do perc<-c(1:234/234) which looks like a bunch of numbers from 0 - 1. In Excel (which I try not to use at every possible occaison) you can use a VLOOKUP function to say choose the rows from the perc vector that are the closest match to the s...

...e goal: seperate objects according to their (row- or even column-)position. I tried something like library(MASS) parcoord(table[,c(1,2)], col = c("green", "yellow")) but as I figure out, the colors of the lines/points plotted, alternate, meaning all points referring to uneven rownumbers are colord in green and respectivley all even rownumbers in yellow. Same with three or more colors; it just continously goes through the vector of colors, right? Acoordingly, my questions concerns on how the plot function uses col and if there is any way to "manipulate". I looked up t...

...ain the corresponding correlation matrix (x) for this scatterplot. Second, use "seq(along = x)[x > 0.9]" to find the positions of the small pictures with 0.9 correlation, but "seq" can just find the sequence position row by row for the matrix, not a real position (like "rowNumber, colNumber"). Is any function for that? Third, use "Symbols" to plot the circle on these small pictures, but seems it can't do that. Also, I don't know how to adjust the thickness and radius of the circle plotted by "Symbols". Please give me some ideas! Thank y...

Hi, I've kind of a tricky question, which I don't know how to solve yet: I get multiple dataframes loaded (readRDS) in a loop function. Each loaded dataframe contains two columns one with a var-name and one with a value. The rownumber (order) is very important as it is a value of the rank (1:x). A example with a similar looped structure: df1 <- data.frame(var=c("A","B","C","D"),value=c(12,5,4,2)) df2 <- data.frame(var=c("B","A","G","C",&quo...
