similar to: problem with the behaviour of dashed lines in R plots

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.

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 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

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)

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

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

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

Can anyone help with scripting the commands below? 1. Add/create a new column to df and name it as ShortPause . 2. Convert ShortPause as a factor variable. 3. ShortPause will have two levels (short and long). Assign short if pause is smaller than 0.1, and assign long otherwise. 4. How many ?syntax==intransitive? observations were realized with a tap (tapped==Tapped)? (Use xtabs() and ftable() to

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.

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 haven?t found rules for logical operators. I need to select data according the following rule: Condition A & (Condition B | Condition C) How should I write it?? Is Condition A & Condition B | Condition C correct or will R execute (Condition A & Condition B) | Condition C ? Thanks for your help. Delphine Fontaine Delphine Fontaine Statistician Statistics
