[R] Function question
Hi. I was wondering how I can write a function that generates the outcome values for a user specified equation. For example, function(x^2, 4) will return back 16 and function(x^3 - 10, 2) will give back -2... I've been playing around with various lines of code but somehow, I just cannot get R to recognize the equation that I pass to it is just a random variable and doesn't need to be initialized... -- View this message in context: http://www.nabble.com/Function-question-tp25619434p25619434.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Plotting two qqnorm plots:
Hi all, Does anyone know how to plot overlapping qqnorm plots on the same window? Suppose I have data in the vector x and y: qqnorm(x) lines(qqnorm(y)) I though these two lines will do the job... However, lines doesn't seem to work. Anyways, thanks in advance! -- View this message in context: http://www.nabble.com/Plotting-two-qqnorm-plots%3A-tp25352893p25352893.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Re moving the numbers of the X/Y axis
Hi all, Suppose I have some data that I plot using the histogram command - ie. hist(x) Is there an option that will allow me to remove the numbers that appear along the X and Y axis as I'm just interested in the overall distribution of the data and not the actual values?

[R] Sequence generation
Hey guys, I was wondering how to create this sequence: 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3... with the '1, 2, 3' repeated over 10 times. Also, is there a simple method to generate 1, 1, 1, 2, 2, 2, 3, 3, 3?

[R] Loess question

[R] Plotting two overlapping curves
Hi. Sorry if this question might have already been asked... I'm trying to plot two curves on the same X-Y coordinate. The par(mfrow) command allows me to plot the two curves on the same window however on different coordinate systems. Is there a way to force the two curves into the same coordinate system?

[R] find duplicates... need help!
Hi all,
Suppose I have x = c('a', 't', 'c', 'y', 'g')
and also y = c('a', 'a', 'g', 's')
If I do something like x%in%y, I obtain a vector like this: [TRUE, FALSE,
FALSE, FALSE, TRUE] which I can easily turn into this: [1, 0, 0, 0, 1].
I was wondering is there anyway for me to get a vector back in return in the
form of: [2, 0, 0, 0, 1]? Essentially, the 2 will tell me that in the first
position of vector 'x', there were two matches found with vector y.
Thanks a ton in advance!

[R] Vector of string
Hi all. Suppose I have a vector of strings ie: [12384, TYU123123, AVC3939, hhr1919, TYU0029] Is there an efficient method that would allow me to return a vector of the position of strings that start with TYU? So essentially, I would like to get back in return [2, 5].

[R] Any method to speed up this problem?
Hi all, Suppose I have a vector like this: [1] STAT1 STAT1 STAT1 STAT1 GAPDH GAPDH GAPDH ACTB ACTB [10] ACTB DDR1 RFC2 HSPA6 PAX8 GUCA1A UBE1L THRA PTPN21 [19] CCL5 CYP2E1 STAT1 THRA PAX8 I would like to produce a vector such that it has the same length as the one above but it tells me where the duplicates are. So essentially, if I could represent each gene symbol as a specific number, and have the duplicates be the same number, that would be ideal. Right now, I'm using the unique command along with two nested for loops to do the job... But it's really taking too long... Any suggestions would be greatly appreciated.

[R] Question regarding dataframes, matrix, frame, etc...
Hi all, As of now, I have a 15x8 matrix (name is asdf). The first seven columns contain numbers while the last column contains a string. The class of each column is character. When I use the plot function to display a scatter plot between any of the two columns, ie. plot(asdf[, 1], asdf[, 2]) everything works fine. However, if I want to use the command pairs to show all combination of scatter plots between the first seven columns (without the columns of strings), it gives me a error message telling me that I'm passing a non-numeric arguement to 'pairs'. As a result, I changed the original matrix into a dataframe via. as.data.frame(asdf) so the columns are of the class factor. However, when I now utilize the pairs command to plot the scatterplots of the first seven columns, the scatterplots are totally off. I think that the pairs command changes all the factor columns into numeric columns - and by performing this class transformation, the values within each column are also physically changed. I'm just really lost. Is there a way to utilize the pairs command in my setting? Or is there a method to change the class of each column without physically altering the values? Anyways, thanks in advance!!! -- View this message in context: http://www.nabble.com/Question-regarding-dataframes%2C-matrix%2C-frame%2C-etc...-tp24056147p24056147.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Creating this vector, any suggetions?
Suppose I have the first vector: c(1, 6, 8, 9) I will like to create a second vector of size 10 composed of 0 and 1's. The second vector will be composed of four 1's and six 0's.

[R] need help with strsplit function
Hi, if I have this string: a.b.c.d and I use this function: unlist(strsplit(a.b.c.d, \\.)), I get this as my output: a, b, c, and d.
