Sigh. I never load packages in .Rprofile to avoid the irreproducibility trap. Might seem drastic to some, but I don't feel much pain because I almost always edit my code in a file rather than on the fly at the console, and re-run it frequently from a fresh R process to check my progress. -- Sent from my phone.

hi david Thank you very much for the hack of draw.circle that you proposed me. I don't understand some part of the code, why do you pass radius as a vector in the function (if I understand well the purpose of the for loop) ? Also what is ymult? If I set the radius to the value 0.85 as I wanted (so as a scalar), I don't see any difference in the result when I call this function

dear R users, I would like to fill a circle with yellow stripes instead of a uniform yellow color. To draw the circle I used the following command after having loaded the (very nice !) plotrix library : library(plotrix) pdf("MWE.pdf",width=8, height=8)

Sorry for that. Yes my question was whether or not and how is it possible to fill a circle of yellow stripes in R? Is it something that I have to precise in the color argument?

dear R-users, I am facing a quite regular and basic problem when it comes to dealing with datasets, but I cannot find any satisfying answer so far. I have a messy dataset of galaxies like that : And XVIII 000214.5+450520 0.69 17 9 0.00 -8.7 26.8 6.44 6.78 < 6.65 -44 0.5 MESSIER031 0.6 1.54 PAndAS-03 000356.4+405319 0.10 17 0.00 -3.6 27.8 4.38

Is this a fixed width format? If so, read.fwf() in base, or read_fwf() in the readr package will solve the problem. You may need to trim trailing spaces though.

dear Jim, Thanks for your reply and your proposition. I forgot to provide the header of the dataframe, here it is: ================================================================================ Byte-by-byte Description of file: lvg_table2.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations

dear Jim, Yes I fixed the problem. Thanks again all of you for your contribution! This worked : start <- c(1, 20, 35, 41, 44, 48, 53, 59, 64, 70, 76, 78, 83, 88, + 93, 114, 122, 127) data1<-read_fwf("lvg_table2.txt",skip=70, fwf_widths(diff(start))) Well now I know how to deal with fixed-width files :) Cheers Jean-Philippe On 05/10/2017 18:42, jim

hi Sarah, Thanks a lot for having taken time to answer me and for your reply. I wonder how I missed this solution. Indeed plotting the line with the 2 extreme data points works perfectly.

dear R users, I am performing a linear regression with lm, and I would like to plot the regressor in dashed lines. I know that the lty=2 option is the way out, but it has a very strange behaviour: the line starts dashed but then the spaces between each dash becomes very tiny and so the line become somehow continuous for the human eye. Do you know how to fix that problem, in order to have a

You should be able to use that header information to create the correct parameters to the read_fwf function to read in the data.

Hi, It's because you are plotting a line between each of the points in your data frame, and they are very close together: > cbind(df1$B,predict(regressor,df1)) [,1] [,2] 1 1.410832 -13.96466 2 1.589383 -15.21169 3 1.446662 -14.21491 4 1.488665 -14.50826 5 1.487035 -14.49687 6 1.497347 -14.56890 7 1.458070 -14.29458 8 1.568134 -15.06328 9 1.543364 -14.89029 10 1.513473

Dear All: Thank you very much for all of you. I just have one more thing. Is there a way to fill the borders with small dots, may be different sizes. I tried to do it, but it looks ugly. Here what I tried: library(plotrix) plot(0:10, 0:10, type="n",axes=FALSE,xlab="",ylab="") #### 0:5, draw.circle(4,5,radius=3,border="#ff0000aa", lwd=75)

It looks like fixed width. I just used the last position of each field to get the size and used the 'readr' package; > input <- "And XVIII 000214.5+450520 0.69 17 9 0.00 -8.7 26.8 6.44 6.78 < 6.65 -44 0.5 MESSIER031 0.6 1.54 + PAndAS-03 000356.4+405319 0.10 17 0.00 -3.6 27.8 4.38 2.8 MESSIER031
