Hi, Is there a function which counts the frequencies of the occurence of a number within an interval? for example I have this vector: x <- c(1, 3, 1.2, 5, 5.9) and I want a vector that gives me the frequencies within an interval of 2, beginning at 0 (so the intervals are 0-2, 2-4, 4-6 and so on) so I get these frequencies: 2, 1, 2 Which functions do I have to use for this purpose?

Hi, I have this variable; x <- c("test_01.log") and I want to extract the number (01) out of the variable. So that I get; > x [1] 1 I tried strsplit, but I don't know how to refer to the result. Can someone help me with that? [[alternative HTML version deleted]]

thanks for the great help! But I have one additional question (hope I can work alone then); I want to replace the values of a vector, like this: x <- c(1,2,2,3,3,4,4,4,5,1) x[x==1] <- c(12) x[x==2] <- c(13) x[x==3] <- c(17) x[x==4] <- c(20) x[x==5] <- c(22) is there a way to do that just in one or two code lines? I tried x[x == c(1:5)] <- c(12,13,17,20,22) but that

Hi, I have a data frame with several columns. Now I want to transfer the data into a new variable (also a data frame), but I only want a part of the data, defined by a rule ... for example; I have following data frame: row1 row2 row3 x 2 3 x 1 4 y 5 3 y 2 3 I know want a data frame, only with lines containing x in row1. I know how to do that for one row (f <-

Hi, I try to write an own function in R. I want a summary table with descriptive statistics. For example, I have this data.frame: d <- data.frame(c(rep("m",5), rep("f",5)), c(1:10)) names(d) <- c("x", "y") d x y 1 m 1 2 m 2 3 m 3 4 m 4 5 m 5 6 f 6 7 f 7 8 f 8 9 f 9 10 f 10 now I want to get the mean and

Is there an easy way to add a text into an R-plot and place it in the upper left corner? Like that: -------------------------------- | (a) | | | | | | | | | | |

Hi, can someone help me; I don't understand why this code doesn't do what it's supposed to do; x <- c("F+", "F+") x <- sub("F+", "F", x) x [1] "F+" "F+" (I want "F" "F") when I try this; x <- c("F+", "F+") x <- sub("+", "", x) x I get an error

Hi, If I have following vector; x <- c(1,1,1,2,2,3,4,4,5) and I want to change values in the range of 1 to 3 into the value 1, how can I do that? I tried x[x == c(1:3)] <- c(1) but than I get; x [1] 1 1 1 2 1 1 4 4 5 R doesn't change the 2 into a 1. But why?

Hi, I have a problem with the R syntax. It's perhaps pretty simple, but I don't understand it ... I can extract a column from a data.frame with the following code for example ... b$row1[b$row1 == "male"] so I see all male-entries. But I cannot extract all lines of a data.frame depending on this criterium; only.male <- b[b$row1 == "male"] With that, I

Hi, is there a way to increase the distance beween the plot (or plot- region) and the main-title? I haven't found anything via ?par(). Thanks for any help!

Hi, is there a way to define, that a line drawn via abline() should only go from for example -2 to 1 on the x-axis (with something working similiar to xlim()) ? thanks for any help!

Hi, I have added a second y-axis via axis() to a plot. Then I tried to add an y axis title. But the axis() function seems to have no argument like ylab. and if I add a title with title() the text is centered at the first axis, not the second defined one. Is there a way to add an axis-title that orientates it's position at the last defined axis?

Hi, I'd like to change the y-tickmarks of a boxplot. But it doesn't work with yaxp (like I would do it in a plot-function). Can someone help me out?

Hi, I want to draw a boxplot and I want to get rid of the surrounding box. So that there are only the axis lines left on the bottom and on the left. I tried a litte bit with box() but I dont get it the way I want. Can somebody help me out?

Hi, I have a problem sorting and selecting entries within a data-frame and I don't know if it is possible to solve it with R ... (probably yes, but I have no idea how). Following Data; row1 row2 a 12 pos NA a 3 neg NA a 5 neg NA a 11 pos NA I want to extract the values in row 2 in the lines with an "a" in row1. But I want to have two vectors: vector x with all
