...are many sub experiments within the main experiment. I would like to draw a bar plot showing the number and type of sub_experiments done for each main_exp. For instance if the Main_Exp is 6, I would like to group the sub exp's for the main_exp and show that there were two sub_exp's done an ELISA and a FCM and that the ELISA was done once and the FCM was done twice. Similarly for Main_Exp 7 I would like to show that for there were ELISA,FCM,qPCR,Telometry done and that they had a count of 3,3,2,5 respectively. This is what my dataset looks like: Main_Exp_Name Sub_Exp_Name Sub_Exp_Cou...

Hello, I am trying to fit my Elisa results (absorbance readings) to a standard curve. To create the standard curve model, I performed a 4-parameter logistic fit using the 'drc' package (ExpectedConc~Absorbance). This gave me the following: > FourP A 'drc' model. Call: drm(formula = Response ~ Expected, data = S...

Dear R users,[IF THE FORMAT OF MY EMAIL IS NOT CLEAR, I HAVE ATTACHED A TEXT FILE FOR A CLEAR VIEW] I would like to use the R output file in Fortran. my file Is exactly in the following format. ELISA/BOTTO wATER INN FROM 1900 11 1 TO 1996 12 31 1901.11. 1 447.000 1901.11. 2 445.000 1901.11. 3 445.000 1924.11. 4 445.000 1924.11. 5 449.000 1924.11. 6 442.000 1924.11. 7 445.000 so you can see that there is a single space, in between these lines and also a single space from...

...with a Seemingly Unrelated Regression. However because of the characteristics of the data I'd like to do it with a negative binomial estimation. Would anybody know how to implement a Seemingly Unrelated Negative Binomial (SUNB) estimation in R? Thank you in advance for your help.

Hi 1Rnwb, I am a technical support for Hitachi Solutions and I saw your post regarding ELISA analysis. When I opened up your .csv file, I noticed it was a Luminex file from the Data Collector 1.7 software. My company developed a multiplex data analysis software for the Luminex platform called http://www.miraibio.com/masterplex-qt/qt-luminex-quantitative-data-analysis-software.html Maste...

Hello R guru's I am a newbie to R, In my research work I usually generate a lot of ELISA data in form of absorbance values. I ususally use Excel to calculate the concentrations of unknown, but it is too tedious and manual especially when I have 100's of files to process. I would appreciate some help in creating a R script to do this with minimal manual input. s A1-G1 and A2-G2 are...

...licates in each condtion (i.e. over 3 colums), not however across the whole data frame. Hence my question, does amelia need some sort of 'grouping', i.e. how do I specify how many columns of my data frame should be used for imputation? Any help is greatly appreciated. Thank you!
