Given the string > mystr <- "(Preconsuntivo del giorno gas 10 maggio 2007)Tj" I'm trying to detect and eliminate the string ")Tj" at the very end of mystr by means of gsub(rx2,"",mystr) BUT preparing the matching regexp string a warning pops up > rx2 <- "\)Tj$" Warning messages: 1: '\)' is an unrecognized escape in a

1. Emma is performing an experiment that requires individual handling of some animals. The sizes of the animals are lognormally distributed: The natural logarithms of their sizes has a normal distribution with mean 3 and standard deviation 0.4. The time (in minutes) it takes to handle each animal is given by 10 + s · 1.5 + eε for animals with s ≤ 20 20 + s · 0.8 + eε for animals with s > 20

Sorry for the verbose example. I want to row bind two matrices, and all works except I want the column labelled "row" to be sequential in the new matrix, shown as "mat3" here, i.e. needs to be 1:6 and not 1:3 repeated twice. Any suggestions? Thanks J > colnm1 <- c("row","ti","counti") > colnm2 <-

Hola, ¿qué tal?: Tengo la siguiente duda: Para el caso del Cosinor Simple: Y = M + A * cos(2*pi*t/T + phi) + error Cuando T conocido, podemos asumir: Y = M + beta * X1 + gamma * X2 + error, siendo X1 = cos(2*pi*t/T) y X2 = sin(2*pi*t/T) En este caso (Cosinor simple) el modelado lo llevo a cabo del siguiente modo: lm( y ~ X1 + X2) Para el caso de componentes múltiples: Y = M + ?Aj *

To all moderators i guess, my question was probably not clear this is not a homework, i am trying to understand R by doing some exercise in my book. I will however participate a course in R in august and thought it could be good to have some knowledge before. I hoped for help from you since i have no instructor to ask, that would have been my first choice. thanks anyway Lotta

Hi all, just a minor thing: Why does `doveadm proxy list` repeat the header line after each entry? Too me, that just makes the output harder to read. So instead of this: root at mail1 ~ # doveadm proxy list username proto src ip dest ip port info at domain1.de imap 80.152.196.98 222.133.127.53 993 username service src-ip dest-ip

Hi everyone! May I request again for your help? I need to make some codes using if else statements... Can I do an "if-else statement" inside an "if-else statement"? Is this the correct form of writing it? Thank you.=) Example: for (v in 1:6) { for (i in 2:200) { if (v==1) (if max(x*v-y*v)>1 break()) if (v==2) (if max(x*v-y*v)>1.8 break()) if (v==3) (if

Hi everyone, I?m trying to do a spaghetti plot and I know I?m doing all wrong, It must be. What I need: 15 subjects, each with measurements over 5 different times (t1, ..., t5), and the variable that I need to represent in the spaguetti plot is given by: PCR = b0 + b1 * ti + epsilon B0, - baseline of each subject B1 - trajectory of each subject over time (so multiply by t) Epsilon - error

Hi, How can I create an NA? for example, i have this program but it has errors > x=scan() 1: 1 2 3 4 5 6: Read 5 items > "na"*x Error in "na" * x : non-numeric argument to binary operator what should I multiply x so that I will get an NA? And I really need to multiply that with my x vector. I need this output: (na,na,na,na,na) Thank you for your time and help!=) --

Hey everybody, Is it alright to run two TDM400s on the same machine? If it is, how would one differentiate between the channels on each card? So, if I'm running strait FXS and my first card is fxsks 1-4, would the second be fxsks 5-8? Would there be any interrupt problems? Any help would be great! Thanks!

Hi all, May I request for your help if you have time and if you have an idea on how to do this. I want to add three vectors... And my goal is to obtain the sum of the vectors, ignoring the vector of "na"... Here is what i did in R.. I'm adding the three vectors, e,z,k, and my objective is to get an answer = -23. I tried putting the na.omit but it did not work. Thanks. > z [1]

Hi Rosa, You pass a vector to ggplot, which expects a data.frame. I am sure you meant to do this: point7$y_point7 <- point7$beta0_7 + point7$beta1_7*point7$time + point7 $epsilon_7 ggplot(point7, aes(time, y_point7)) + geom_line() HTH Ulrik On Wed, 19 Jul 2017 at 20:37 Rosa Oliveira <rosita21 at gmail.com> wrote: > Hi everyone, > > I?m trying to do a spaghetti plot and I
